Fix quotad RPC options use-after-free bug in gluster
In cli/src/cli.c:cli_quotad_clnt_rpc_init(), dict_unref (rpc_opts)
causes the options to be freed while code in rpc/rpc-transport/socket
still relies on it. The options are corrupted when memory is reallocated,
which sometimes leads to a crashes on NetBSD when socket_connect()
attempted to read options.
Fix the problem by not doing the dict_unref(). Make sure the rpc_opts
are freed on error, though.
