[Drbd-dev] [PATCH] drbd: fix a bug with two-primaries configuration

[Rui Xu]

There is a bug when execute 'drbdsetup disconnect' in
two-primaries configuration.

When 'drbdsetup disconnect' is called by user, two primary
nodes will going to outdated in do_change_cstate, then the
command will failed since there is no UpToDate node.

Fix it by modify the judgment condition in do_change_cstate.
