msg/async/rdma: use gid_idx as index to get gid

1. use gid_idx as parameter to get gid instead of getting the first(0) gid
by default.
int ibv_query_gid(struct ibv_context *context, uint8_t port_num, int
	index, union ibv_gid *gid)
2. gid is initialized in class type declaration, there's no need to
initialized in the member construction list.
