blktrace: fix trace mutex deadlock
commit 2967acbb257a6a9bf912f4778b727e00972eac9b upstream.
A previous commit changed the locking around registration/cleanup,
but direct callers of blk_trace_remove() were missed. This means
that if we hit the error path in setup, we will deadlock on
attempting to re-acquire the queue trace mutex.
Fixes: 1f2cac107c59 ("blktrace: fix unlocked access to init/start-stop/teardown")
