scsi: ufs: fix pm_runtime count in reset flow

ufshcd_probe_hba() puts pm_runtime all the time. So, during the reset flow,
we need to get one.

pm_runtime_get_sync (1)
ufshcd_async_scan
pm_runtime_get_sync (2)
ufshcd_hold_all
ufshcd_probe_hba
 - pm_runtime_put_sync (1)
 - ufshcd_reset_and_restore
   - ufshcd_detect_device
    - ufshcd_host_reset_and_restore
       - ufshcd_probe_hba
       - pm_runtime_put_sync (0)

ufshcd_release_all
pm_runtime_put_sync (-1)
