3975688563 rack: honor prior socket buffer lock when doing the upcall
While partially reverting D24237 with D29690, due to introducing some
unintended effects for in-kernel TCP consumers, the preexisting lock
on the socket send buffer was not considered properly.

916c61a5ed Fix handling of errors from pru_send(PRUS_NOTREADY)
PRUS_NOTREADY indicates that the caller has not yet populated the chain
with data, and so it is not ready for transmission.  This is used by
sendfile (for async I/O) and KTLS (for encryption).  In particular, if
pru_send returns an error, the caller is responsible for freeing the
chain since other implicit references to the data buffers exist.

For async sendfile, it happens that an error will only be returned if
the connection was dropped, in which case tcp_usr_ready() will handle
freeing the chain.  But since KTLS can be used in conjunction with the
regular socket I/O system calls, many more error cases - which do not
result in the connection being dropped - are reachable.  In these cases,
KTLS was effectively assuming success.

So:
- Change sosend_generic() to free the mbuf chain if
  pru_send(PRUS_NOTREADY) fails.  Nothing else owns a reference to the
  chain at that point.
- Similarly, in vn_sendfile() change the !async I/O && KTLS case to free
  the chain.
- If async I/O is still outstanding when pru_send fails in
  vn_sendfile(), set an error in the sfio structure so that the
  connection is aborted and the mbuf chain is freed.

7d2608a5d2 tcp: Make error handling in tcp_usr_send() more consistent
- Free the input mbuf in a single place instead of in every error path.
- Handle PRUS_NOTREADY consistently.
- Flush the socket's send buffer if an implicit connect fails.  At that
  point the mbuf has already been enqueued but we don't want to keep it
  in the send buffer.

f190f9193b Fix fsck_ufs segfaults with gjournal (SU+J)
The segfault was being hit in ckfini() (sbin/fsck_ffs/fsutil.c)
while attempting to traverse the buffer cache to flush dirty buffers.
The tail queue used for the buffer cache was not initialized before
dropping into gjournal_check(). Move the buffer initialization earlier
so that it has been done before calling gjournal_check().

af2253f61c mmccam: Add two new XPT for MMC and use them in mmc_sim and sdhci
For the discovery phase of SD/eMMC we need to do some transaction in a async
way.
The classic CAM XPT_{GET,SET}_TRAN_SETTING cannot be used in a async way.
This also allow us to split the discovery phase into a more complete state
machine and we don't mtx_sleep with a random number to wait for completion
of the tasks.
For mmc_sim we now do the SET_TRAN_SETTING in a taskqueue so we can call
the needed function for regulators/clocks without the cam lock(s). This part is
still needed to be done for sdhci.
We also now save the host OCR in the discovery phase as it wasn't done before and
only worked because the same ccb was reused.
