Andriy Voskoboinyk d25646a482 iwn: drop unneeded bus_dmamap_sync() calls.
1) They are using wrong tag (Tx) + map (Rx) combination.
2) Rx descriptor is already synchronized in iwn_notif_intr()
3) It's not needed for transmitted data since device does not change
mbuf contents.

Tested with Intel 6205 (amd64), STA mode.
