scsi: lpfc: Check queue pointer before use

Browse source 
The queue pointer might not be valid. The rest of the code checks the
pointer before accessing it. lpfc_sli4_process_missed_mbox_completions is
the only place where the check is missing.

Fixes: 657add4e5e ("scsi: lpfc: Fix poor use of hardware queues if fewer irq vectors")
