bluez5: use initial SCO RX wait workaround only for USB controllers

Browse source 
Kernel-provided MTU does not work for USB controllers and the correct
packet size to send can be known currently only from RX. So we are
waiting for RX to get it.

The known problem is USB-specific, we shouldn't need the workaround for
other transport types.

Don't wait for POLLIN for non-USB controllers on connect, but ready
things on POLLOUT as usual.

For non-USB controllers, pick some sensible packet sizes to use
initially, before we switch to same size as for RX.
