This patch changes the size of the input and output buffers to the same size of
the channel MTU. The channel MTU, in turn, is the L2CAP MTU for BR/EDR
channels, and the ATT MTU for LE channels. This value can change between calls
to channel_handler if a GATT MTU exchange procedure is performed, which is only
supported by LE channels.
