nvme: Supress noise messages

When we're suspending, we get messages about waiting for the controller
to reset. These are in error: we're not waiting for it to reset. We put
the recovery state as part of suspending, so we should suppress these as
a false positive.

Also remove a stray debug that's left over from earlier versions of
the recovery code that no longer makes sense.
