Subject: [PATCH][next] z3fold: remove redundant assignment to bud

From: Colin Ian King <colin.king@...onical.com>

The variable bud is initialized with the value 'LAST' which is never
read and bud is reassigned later on the return from the call to the
function handle_to_buddy. This initialization is redundant and
can be removed.

Addresses-Coverity: ("Unused value")
