Remove calling the deprovision command and use a simpler way to fulfill

There's been a report recently of mbufs with data that crosses a page
boundary. It seems those mbufs are generated by the iSCSI target
system:
https://lists.xenproject.org/archives/html/xen-devel/2021-12/msg01581.html
In order to handle those mbufs correctly on netfront use the bus_dma
interface and explicitly request that segments must not cross a page
boundary. No other requirements are necessary, so it's expected that
bus_dma won't need to bounce the data and hence it shouldn't
introduce a too big performance penalty.
Using bus_dma requires some changes to netfront, mainly in order to
accommodate for the fact that now ring slots no longer have a 1:1
match with mbufs, as a single mbuf can use two ring slots if the data
buffer crosses a page boundary. Store the first packet of the mbuf
chain in every ring slot that's used, and use a mbuf tag in order to
store the bus_dma related structures and a refcount to keep track of
the pending slots before the mbuf chain can be freed.

Now that vtblk uses busdma, it keeps important information inside its
request structures. The functions used for kernel dumps synthesize
their own request structures rather than using structures initialized
with the necessary bits for busdma.
Add busdma-bypass paths. Since dumping writes contiguous blocks of
physical memory, vtblk doesn't need busdma in that case.

The break-before-make requirement poses a problem when promoting or
demoting mappings containing thread structures: a CPU may raise a
translation fault while accessing curthread, and data_abort() accesses
the thread again before pmap_fault() can translate the address and
return.
Normally this isn't a problem because we have a hack to ensure that
slabs used by the thread zone are always accessed via the direct map,
where promotions and demotions are rare. However, this hack doesn't
work properly with UMA_MD_SMALL_ALLOC disabled, as is the case with
KASAN configured (since our KASAN implementation does not shadow the
direct map and so tries to force the use of the kernel map wherever
possible).
Fix the problem by modifying data_abort() to handle translation faults
in the kernel map without dereferencing "td", i.e., curthread, and
without enabling interrupts. pmap_klookup() has special handling for
translation faults which makes it safe to call in this context. Then,
revert the aforementioned hack.

Currently SO_REUSEPORT_LB silently does nothing when set by a jailed
process. It is trivial to support this option in VNET jails, but it's
also useful in traditional jails.
This patch enables LB groups in jails with the following semantics:
- all PCBs in a group must belong to the same jail,
- PCB lookup prefers jailed groups to non-jailed groups
This is a straightforward extension of the semantics used for individual
listening sockets. One pre-existing quirk of the lbgroup implementation
is that non-jailed lbgroups are searched before jailed listening
sockets; that is preserved with this change.
