scsi: lpfc: Fix defects reported by Coverity Scan
Addressed the following reported defects:
** CID 1411552: Control flow issues (MISSING_BREAK)
/drivers/scsi/lpfc/lpfc_sli.c: 13259 in lpfc_sli4_nvmet_handle_rcqe()
** CID 1411553: Memory - illegal accesses (OVERRUN)
/drivers/scsi/lpfc/lpfc_sli.c: 16218 in lpfc_fc_frame_check()
** CID 1411553: Memory - illegal accesses (OVERRUN)
Overrunning array "lpfc_rctl_names" of 202 8-byte elements at element
index 244 (byte offset 1952) using index "fc_hdr->fh_r_ctl" (which
evaluates to 244).
** CID 1411554: Null pointer dereferences (REVERSE_INULL)
/drivers/scsi/lpfc/lpfc_nvmet.c: 2131 in lpfc_nvmet_unsol_fcp_abort_cmp()
** CID 1411555: Memory - illegal accesses (UNINIT)
/drivers/scsi/lpfc/lpfc_nvmet.c: 180 in lpfc_nvmet_ctxbuf_post()
