    fixes problem with duplicate TXREQ packets
    
    When Asterisk receives an IAX2 TXREQ packet, try_transfer()
    will call store_by_transfercallno() to link the chan_iax2_pvt
    struct into iax_transfercallno_pvts. If a duplicate TXREQ
    packet is received for the same call, the pvt struct will be
    linked into iax_transfercallno_pvts multiple times.  This patch
    fixes this.  Thanks rain for debugging this and providing a patch!
