drbd: take error path in drbd_adm_down if interrupted by signal ...
drbd_adm_down() does adm_detach(), which can fail with various error
codes, or be interrupted by a signal.
The interrupted by signal case was not properly handled,
leading to
block drbd0: ASSERT( mdev->state.disk == D_DISKLESS &&
mdev->state.conn == C_STANDALONE ) in drbd/drbd_worker.c
and further to destroying objects while still in use, and resulting crashes.
Detect the interruption, and take the error path out.
