[SCSI] lpfc 8.2.7 : Miscellaneous Fixes

Miscellaneous Fixes:
- Fix bug in mbox sysfs interface that locked in EAGAIN if discovery stalled.
- Fix missing error message when npiv and loop are true when link up occurs.
- Fix panic in lpfc_scsi_cmd_iocb_cmpl: scsi_buf was NULL, but created
  race conditions with other code paths.
- Fix error in sysfs mailbox structure that didn't rezero on next use.
- Add missing mempool_free() to attachment failure path
- Fix missing put of ndlp structure during driver unload.
- Fix applications unable to send mailbox commands during discovery.
- Remove unused argument (type) from function lpfc_post_buffer() API
- Fix vport name is not shown after hbacmd vportcreate.
- Remove repeated code statements.
