[SCSI] lpfc 8.1.12 : Misc bug fixes and code cleanup
Misc bug fixes and code cleanup:
- Fix system hang while running on systems with IOMMU
- Fix use after free issues with rports
- Don't free mailbox structure if it's still on the mboxq list
- Decrement txq_cnt rather than txcmplq_cnt when parsing the txq list
- Use msleep for long delays to prevent soft lockup bug check
- Don't remove node during dev_loss_tmo if discovery is active
- Fix memory leaks in get/reset statistics and link attention paths
- Fixed lpfc_ns_rsp to handle entire GID_FT response.
- mbox interface should use MAILBOX_CMD_SIZE rather than sizeof(MAILBOX_t)
- Fixed bug check in add_timer.
- Fixup messages 0116, 0117, and 0128 to report ELS I/O tag.
- Remove unused parameter to lpfc_cleanup.
- Change mailbox timeout handling.
- Remove unused buflist. Code cleanup.
