The function __ata_qc_complete() is always called with a qc that already has been dereferenced and so is guaranteed to be non-NULL (as otherwise the kernel would have crashed). So remove the warning for a NULL qc as it is useless. Furthermore, the qc passed to __ata_qc_complete() must always be marked as active with the ATA_QCFLAG_ACTIVE flag. If that is not the case, in addition to the existing warning, return early so that we do not attempt to complete an invalid qc. Finally, fix the comment related to clearing the qc active flag as that operation applies to all devices, not just ATAPI ones.

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.
