gpu: pvr: remove sQProcessResource/OSLockResource interface
The relevent parts are already protected by pvr_lock(), so no
need for sQProcessResource, which was anyway racy and required
the occasional retrying of any operations performed on the
protected object.
The OSLockResource interface thus becomes unused, so remove it
too.
