This change adds timeouts to the RNC suspension wait.  It makes the
suspend and resume timeouts the same.

The previous resume timeout of 5 ms was too short, and timeouts were
seen in resumptions of devices in the abort task/LUN reset path - which
would receive an RNC resumed message within a tenth of a second later.
