tbf: Don't change type from CCCH to PACCH without ack
Currently the CCCH flag is cleared and the PACCH flag is set when a
multislot upgrade is scheduled for a downlink TBF, even if the MS has
never confirmed in any way that the PACCH really exists. This can
happen if the MS did not receive the DL IMM.ASS. Since the CCCH flags
gets cleared in that case, the IMM.ASSS is never retried and all
subsequent PACKET DOWNLINK ASSIGNMENTS will fail.
This commit delays the update of these flags until the MS has
responded with a corresponding CONTROL ACK.
