qcacmn: avoid of HTC buffer double free in HTC send failure case

HTC buffer is freed in enqueue failure case. Then it is requeued to
htt_htc_pkt_misclist also. In deinit flow, misclist entry should be
cleared, so buffer double free is hit in this stage. Make a change
to not requeue this frame to misclist.
