scsi: lpfc: Clear outstanding active mailbox during PCI function reset
Mailbox commands sent via ioctl/bsg from user applications may be
interrupted from processing by a concurrently triggered PCI function
reset. The command will not generate a completion due to the reset. This
results in a user application hang waiting for the mailbox command to
complete.
Resolve by changing the function reset handler to detect that there was an
outstanding mailbox command and simulate a mailbox completion. Add some
additional debug when a mailbox command times out.
