Subject: [PATCH v2 0/3] selftests: ublk: kublk: fix feature list

This patch simplifies kublk's implementation of the feature list
command, fixes a bug where a feature was missing, and adds a test to
ensure that similar bugs do not happen in the future.

Signed-off-by: Uday Shankar <ushankar@...estorage.com>

Changes in v2:
- Add log lines to new test in failure case, to tell the user how to fix
  the test, and to indicate that the failure is expected when running
  an old test suite against a new kernel (Ming Lei)
- Link to v1: https://lore.kernel.org/r/20250916-ublk_features-v1-0-52014be9cde5@purestorage.com
