Commit22089c2180("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().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
