9p: drop broken unused error path from p9_conn_create()
Post p9_fd_poll() error path which checks m->poll_waddr[i] for PTR_ERR value has the following problems. * It's completely unused. Error value is set iff NULL @wait_address has been specified to p9_pollwait() which is guaranteed not to happen. * It dereferences @m after deallocating it (introduced by 571ffeaf and spotted by Raja R Harinath. * It returned the wrong value on error. It should return poll_waddr[i] but it returnes poll_waddr (introduced by 571ffeaf). * p9_mux_poll_stop() doesn't handle PTR_ERR value. It will try to operate on the PTR_ERR value as if it's a normal pointer and cause oops. As the error path is bogus in the first place, there's no reason to hold onto it. Kill it.
