tc_etu.c: Removed, because was never used

Since the host side does the parsing of the packets, (not the firmware,
as it was in the old simtrace version), we do not need to check for expired
max waiting time.
Instead, every byte received from the phone is filled into a ring buffer.
As soon as the USB endpoint to the host is not busy anymore, it is sent
to the host over the respective USB endpoint.
