samsung: fix up disconnect

Two issues here, first we dont' need to chain up to the parent
because it's not doing anything we need (it's mainly for PPP-based
devices) and second we need to wait a bit for the disconnect command
to complete by specifying a callback, otherwise the command may get
discarded when the port is shut down afterward.
