nfc: Do not send datagram if socket state isn't LLCP_BOUND
[ Upstream commit 6ec0d7527c4287369b52df3bcefd21a0c4fb2b7c ] As we know we cannot send the datagram (state can be set to LLCP_CLOSED by nfc_llcp_socket_release()), there is no need to proceed further. Thus, bail out early from llcp_sock_sendmsg(). Signed-off-by:Siddh Raman Pant <code@siddh.me> Reviewed-by:
