rpc,glusterd: Set ret to 0 after call to rpc_clnt_submit()

This is to guard against a double STACK_DESTROY in the event that
rpc_clnt_submit() failed and returned -1 anytime after sending the
request over the wire. in which case the stack could be destroyed
twice: once in the callback function of the request and once in
the error codepath of some of the callers of glusterd_submit_request().
