scsi: ibmvscsi_tgt: Remove target_wait_for_sess_cmd()
There is currently a bug with the driver where there is never a call to target_sess_cmd_list_set_waiting(), it only called target_wait_for_sess_cmd(), which basically means that the sess_wait_list would always be empty. Thus, list_empty(&sess->sess_wait_list) = true, (eg: no se_cmd I/O is quiesced, because no se_cmd in sess_wait_list), since commit 712db3eb2c35 ("scsi: ibmvscsis: Properly deregister target sessions") in 4.9.y code. ibmvscsi_tgt does not remove the I_T Nexus when a VM is active so we can fix this issue by removing the call to target_wait_for_sess_cmd() altogether.
