ufs: core: Use scsi_device_busy()
f7772a4 
Use scsi_device_busy() instead of open-coding it. This patch prepares
for skipping the SCSI device budget map initialization in certain cases.

scsi: core: Improve IOPS in case of host-wide tags
0b1fd78 
The SCSI core uses the budget map to enforce the cmd_per_lun limit.
That limit cannot be exceeded if host->cmd_per_lun >= host->can_queue
and if the host tag set is shared across all hardware queues.
Since scsi_mq_get_budget() shows up in all CPU profiles for fast SCSI
devices, do not allocate a budget map if cmd_per_lun >= can_queue and
if the host tag set is shared across all hardware queues.

On my UFS 4 test setup this patch improves IOPS by 1% and reduces the
time spent in scsi_mq_get_budget() from 0.22% to 0.01%.
