glusterd/mgmt: coverity fixes

This patch fixes coverity issues 179, 59.

Problem: control flow won't enter into if block as volname is always
NULL and return value of function synctask_barrier_init is unchecked.

Fix: remove condition checking which is always resulting in false,
and removing if block which is always unreachable. As a result of
removal of condition checking volname became a unused variable,
so remove declaration of volname.

assign return valur of synctask_barrier_init to ret, if it nonzero
value goto out.
