When READ CAPACITY fails, we call cam_periph_invalidate() for some
hopeless ASC/ASCQ combinations and then fall through to test the cache
state. This results in excess commands to the abandoned device that may
take a while to timeout and/or report confusing errors. Instead, call
daprobedone() when the periph is invalid to terminate the probe.
