Previously, if per-CPU MSI-X vectors could not be allocated,
nvme(4) would fall back to INTx with a single I/O queue pair.
This change will still fall back to a single I/O queue pair, but
allocate MSI-X vectors instead of reverting to INTx.

NB: This deeply effected HardenedBSD which had a default value set.
Embarassingly, I allowed the `type' primitive to be passed -1/-1 for
c-addr/u stack input (the effect of which is to pull INT_MAX bytes
from character address negative one in which hilarity ensues over a
black screen in full-on bootlock). Much thanks to Shawn Webb [lattera]
for helping me diagnose.
NB: The mode-ending revisions were initially suspected (and reverted)
but proved to be a red-herring. Proper mode endings will be returning.

It actually doesn't - "device ctl" automatically pulls in ICL, which
would normally be a part of iscsi.ko. However, doing it that way makes
iscsi.ko unloadable, and building ctl.ko without iscsi.ko (using
MODULES_OVERRIDE) results in ctl.ko that is unloadable, due to missing
symbols that would be resolved to iscsi.ko. And since the symbols
are named "icl_whatever", it's not obvious that it's iscsi.ko that's
required.
If there is a better way - let me know.

This significantly improves performance on multi-core servers where there
is any kind of IPv4 reassembly going on.
glebius@ would like to see the locking moved to be attached to the reassembly
bucket, which would make it per-bucket + per-VNET, instead of being global.
I decided to keep it global for now as it's the minimal useful change;
if people agree / wish to migrate it to be per-bucket / per-VNET then please
do feel free to do so. I won't complain.
Thanks to Norse Corp for giving me access to much larger servers
to test this at across the 4 core boxes I have at home.
