scsi: lpfc: Fix NVME io abort failures causing hangs
The nvme-fc transport may call to abort an io on controller reset. If the
driver is out of resources to issue an abort command, it just gives up and
does nothing. The transport expects the lldd to always be able to terminate
an io it has issued. At that point, the controller hangs waiting for
aborted ios to be returned. Note: flaged by "6136" and "6176" error
messages.
Root issue was the adapter mis-allocated the number resources it allocated
for command entries for the adapter.
Convert the driver to allocate command resources based on the number of
xris supported by the FC port - 1 resource for the original command and 1
resource for the abort request.
