transceiver: Fix mixed GSMK / 8-PSK transmission

Input burst construction was declared static causing the first
downlink burst from upstream to determine subsequent burst size
and modulation. Consequently, fixed sequence EGPRS tests would
pass, however, switching between 8-PSK and GMSK bursts would
fail with only one modulation type being transmitted.

Internally generated test sequences '-r' option were not affected
because the bursts are not received through the socket interface.
