Subject: [PATCH 5.10 671/717] scsi: lpfc: Fix scheduling call while in softirq context in lpfc_unreg_rpi

From: James Smart <james.smart@...adcom.com>

commit e7dab164a9aa457f89d4528452bdfc3e15ac98b6 upstream.

The following call trace was seen during HBA reset testing:

With the conversion to blk_io_poll for better interrupt latency in normal
cases, it introduced this code path, executed when I/O aborts or logouts
are seen, which attempts to allocate memory for a mailbox command to be
issued.  The allocation is GFP_KERNEL, thus it could attempt to sleep.

Fix by creating a work element that performs the event handling for the
remote port. This will have the mailbox commands and other items performed
in the work element, not the irq. A much better method as the "irq" routine
does not stall while performing all this deep handling code.

Ensure that allocation failures are handled and send LOGO on failure.

Additionally, enlarge the mailbox memory pool to reduce the possibility of
additional allocation in this path.
