Device3: Fix MTU and default frame sizes
The latest changes to the get_*x_stream() functions to calculate the MTU for
the channel caused default frame size values to be ignored. This change fixes
that by changing the key from "send/recv_frame_size" to "mtu" and then changing
the implementations of make_transport() constrain the frame size values based
on the "mtu" value as well as any device and/or transport-specific limits.
