Currently the NCQ tag is only assigned for FPDMA READ and FPDMA WRITE commands, and for other NCQ commands (such as FPDMA SEND), their NCQ tags are set in the delivery command to 0. So for all the NCQ commands, we also need to assign normal NCQ tag for them, so drop the command type check in hisi_sas_get_ncq_tag() [drop hisi_sas_get_ncq_tag() altogether actually], and always use the ATA command NCQ tag when appropriate.

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 Restructured Text 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.
