dahdi_dynamic: Call dahdi_receive in rx packet handler.

Currently dahdi_receive is called on all channels in the context of the
master dynamic span. If one span (not the master) receive two packets
before the master span received a packet, the older packet on the
dynamic span would end up lost because the "readchunk" for the
channels would be overwritten by the new packet. DAHLIN-245
