bts: Release DL TBF instead of killing in rcv_resource_request
Currently an existing DL TBF is freed immediately, when a resource request is received. This makes sense since the MS might have dropped it when switching to the PDCH signaled via the AGCH for the SBA. But if the TBF still is assumed to exist on the MS side, there might be TFI collisions if the old TBF object is not kept to block its TFI for some time. This commit changes rcv_resource_request to call release() instead of tbf_free() on the DL TBF object (if it exists). Sponsored-by: On-Waves ehf
