In case POLLIN is set, and no new application data has been detected, the ztls_poll_update_ctx() should only return -EAGAIN if no other events are available for the socket. Otherwise, the function may end up busy-looping, in case for example POLLOUT is also monitored for the socket.
Current check verifying that was wrong, as it caused to function to return -EAGAIN even if some other events could've been reported for the socket.
Fixes #75909
