scsi: lpfc: Add REG_VFI mailbox cmd error handling

If lpfc_issue_reg_vfi() returns an error in lpfc_rcv_plogi(), then
execution of lpfc_rcv_plogi() continues and lpfc_reg_rpi() is called, which
allocates an mbuf.  When this REG_RPI mailbox is issued, it inevitably
fails because the VFI is not registered.  However, the REG_RPI failure does
not free the mbuf that was allocated in lpfc_reg_rpi() because there is no
check for mbox error status in lpfc_defer_plogi_acc().

Fix by adding a check in lpfc_rcv_plogi() if lpfc_reg_vfi() fails, then
exit early.  Also, add mailbox status check in lpfc_defer_plogi_acc to
enter the REG_RPI mbox_cmpl functions and free the allocated mbuf.
