scsi: ufs: core: Fix single doorbell mode support
Commit 22089c218037 ("scsi: ufs: core: Optimize the hot path")
accidentally broke support for the legacy single doorbell mode. The
tag_set.shared_tags pointer is only != NULL if shared tag support is
enabled. The UFS driver only enables shared tag support in MCQ mode.
Fix this by handling legacy and MCQ modes differently in
ufshcd_tag_to_cmd().
