ath9k_hw: clean up ath9k_hw_setuprxdesc
The ATH9K_HW_CAP_AUTOSLEEP check is bogus, the rx status area needs to be cleared on all non-EDMA PCI/AHB based chipsets anyway. Limit the memset to the rx status area to improve performance. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
