glusterd: Fix glusterd crash resulting from uninitialised pointer

PROBLEM:
glusterd crashes during replace-brick operation as the
pointer old_brickinfo is dereferenced without being initialised.

FIX:
Have old_brickinfo initialised to point to the brick info of
the brick being replaced before dereferencing it.

TEST:
Ran glusterd in debug mode before and after the fix;
process crash ceased in the latter case.
