ath5k: move rx and tx status structures out of hardware descriptor

move ath5k_tx_status and ath5k_rx_status structures out of the hardware
descriptor since they are not accessed by the hardware at all. they just
contain converted information from the hardware descriptor. since they are only
used in the rx and tx tasklets there is also no use to keep them for each
descriptor.
