Giridhar Malavali 9fe278f44b scsi: qla2xxx: Move log messages before issuing command to firmware 
There is a probability that the SRB structure might have been released by the
time the debug log message dereferences it.  This patch moved the log messages
before the command is issued to the firmware to prevent unknown behavior and
kernel crash

Fixes: 726b854870 ("qla2xxx: Add framework for async fabric discovery")
