scsi: lpfc: code cleanups in NVME initiator base
This patch addresses the smatch issues identified by Dan Carpenter
in http://www.spinics.net/lists/linux-scsi/msg105663.html
The issues are:
drivers/scsi/lpfc/lpfc_hbadisc.c:316 lpfc_dev_loss_tmo_handler()
warn: we tested 'vport->load_flag & 2' before and it was 'false'
Action: removed item from test
drivers/scsi/lpfc/lpfc_hbadisc.c:701 lpfc_work_done()
warn: test_bit() takes a bit number
Action: changed definition so bit number
drivers/scsi/lpfc/lpfc_hbadisc.c:2206 lpfc_mbx_cmpl_fcf_scan_read_fcf_rec()
error: uninitialized symbol 'vlan_id'.
drivers/scsi/lpfc/lpfc_hbadisc.c:2582 lpfc_mbx_cmpl_fcf_rr_read_fcf_rec()
error: uninitialized symbol 'vlan_id'.
drivers/scsi/lpfc/lpfc_hbadisc.c:2683 lpfc_mbx_cmpl_read_fcf_rec() error:
uninitialized symbol 'vlan_id'.
Action: initilized value
drivers/scsi/lpfc/lpfc_hbadisc.c:4025 lpfc_register_remote_port()
error: we previously assumed 'rdata' could be null (see line 4023)
Action: refactored check block
drivers/scsi/lpfc/lpfc_hbadisc.c:4613 lpfc_sli4_dequeue_nport_iocbs()
error: double unlock 'irq:'
Action: removed inner irq reference
