Make et_probe() return BUS_PROBE_DEFAULT such that allow other

driver that has high precedence for the controller override et(4).
Add missing callout_drain(9) in device detach and rework detach
routine.  While I'm here use rman_get_rid(9) instead of using
cached resource id because bus methods are free to change the
id.
