Subject: [PATCH] ceph: return result directly from wait_for_completion_killable()

Simplify the code by returning the result of
wait_for_completion_killable() directly, instead of calling it
separately and then returning 0.

No functional changes are introduced, this is a simple refactor
to streamline the code.
