[PATCH] block/drbd: remove redundant initialization to variable rv

From: Colin Ian King <redacted>

The variable rv is being initialized with a value that is never read
and it is being updated later with a new value.  The initialization is
redundant and can be removed.

Addresses-Coverity: ("Unused value")
