From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx>
This patch adds a scsi_cmd_get_serial() call in _scsih_qcmd() to setup a
valid struct scsi_cmnd->serial_number because mpt2sas_scsih_issue_tm()
still depends upon this being set.
This also includes setting the SHT->unlocked_qcmd=1 for host_lock less mpt2sas
_scsih_qcmd() operation.
