Subject: [PATCH][next] drbd: remove redundant assignment to variable owords

The variable owords is being assigned a value that is never
read, the exit path via label out returns before owords is ever
used again. The assignment is redundant and can be removed.

Cleans up clang scan build warning:
drivers/block/drbd/drbd_bitmap.c:654:3: warning: Value stored to 'owords' is never read [deadcode.DeadStores]
