Currently registering a checksum-enabled (aka PI) integrity profile sets the QUEUE_FLAG_STABLE_WRITE flag, and unregistering it clears the flag. This can incorrectly clear the flag when the driver requires stable writes even without PI, e.g. in case of iSCSI or NVMe/TCP with data digest enabled. Fix this by looking at the csum_type directly in bdev_stable_writes and not setting the queue flag. Also remove the blk_queue_stable_writes helper as the only user in nvme wants to only look at the actual QUEUE_FLAG_STABLE_WRITE flag as it inherits the integrity configuration by other means.

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.
