[PATCH 024/118] drbd: Remove some useless paranoia code

Philipp Reisner

From: Andreas Gruenbacher <agruen@linbit.com>

The open_cnt check is an open-coded D_ASSERT() check.

In case the data.work queue is not empty, it does not really help to
know which drbd_work elements remained on that list: they will be freed
immediately afterwards, anyway.
