[SCSI] qla2xxx: Always serialize mailbox command execution.

Browse source

Original code would incorrectly bypass serialization if the DPC
thread were performing a big-hammer operation (ISP abort).  This
short circuit, though rare, would subsequently stomp on a
secondary thread's mailbox command execution.  Found during
ISP81XX testing.
