glusterd: Added iov error checking in rpc callbacks.

Problem : glusterd was crashing with SIGABRT if rpc connection is failed in
debug mode.

Reason  : It was happening due to iov is passing to assert() before checking
rpc status in rpc call back function (rpc is  calling callback function with
setting rpc status as -1 and passing NULL to iov if connection is failed).

Fix     : Error checking for iov added after checking the rpc status verified
and error messages are added properly .
