ufshci: reject new requests on a failed controllerHEADmain

A failed controller accepted new requests, but nothing ever
completed them, so the caller waited forever. The admin retry
path could also resubmit a request to a dead queue.

Reject new submits and admin retries on a failed controller.
The submit check runs under the queue lock, so it cannot race
with the queue walk in the fail path.
