tbf: Do not kill DL TBF on Packet Resource Request
Currently all active TBF of an MS are killed if a Packet Resource
Request is received from the MS. In general this happens after a RACH
request. This does not happen after a resource request that has been
included into a Downlink Ack/Nack.
Sometimes an UL TBF is requested by an MS via RACH while a DL TBF is
running for instance to send a TCP Ack. This can happen, if a former
request via PACCH did not work.
This commit removes the killing of the DL TBF from
gprs_rlcmac_pdch::rcv_resource_request().
