[SCSI] lpfc 8.1.12 : Round 2 of Miscellaneous fixes

Round 2 of Miscellaneous fixes:
 - Ensure we don't prematurely re-enable IRQs in lpfc_sli_abort_fcp_cmpl().
 - Prevent freeing of iocb after IOCB_TIMEDOUT error.
 - Added code to cleanup REG_LOGIN mailbox command when a LOGO is received.
 - Fix offline window where more work can sneak in after clearing work_ha
 - Use target reset instead of LU reset in bus_device_reset_handler
 - Fixed system hangs due to leaked host_lock.
 - Fixed NULL pointer dereference during I/O with LIP.
 - Fixed false iocb timeout.
 - Fixed name server query response handling.
 - Change rport dev_loss_tmo value when user change lpfc HBA's dev_loss_tmo.
 - Fixed a memory leak in lpfc_sli_wake_mbox_wait.
 - Fixed check for dropped frames.
 - Removed hba queue depth calculation based on device PCI IDs
 - Change min cr_count value specified in comment to agree with setting
