[PATCH 27/30] drbd: get rid of empty statement in is_valid_state

[Philipp Reisner]

From: Roland Kammerer <roland.kammerer@xxxxxxxxxx>

This should silence a warning about an empty statement. Thanks to Fabian
Frederick <fabf@xxxxxxxxx> who sent a patch I modified to be smaller and
avoids an additional indent level.
