Rename patty_ax25_sock.rx_buf to io_buf

Browse source 
Rename patty_ax25_sock.rx_buf to io_buf, as the buffer is not used for
receiving frames from an interface, but rather from reading local data
to write to a remote peer

Other changes:

    * Fix issue wherein patty_ax25_sock.n_maxlen_tx was not used for
      reading local data when sending I frames
