[SCSI] lpfc 8.3.6 : Fix critical errors
Fix errors relating to crashes and hangs.
- Fix crash due to list corruption while unloading driver.
- Fix panic during pci-hot-plug testing.
- Fix panic when unmapping luns.
- Fixed total_scsi_bufs counting could cause exhausted memory.
- Fixed locking issue causing hang.
- Fixed the call from lpfc_new_scsi_buf_s3 to use lpfc_release_scsi_buf_s3.
