[PATCH 4.9 25/78] ath9k_htc: Use appropriate rs_datalen type

[Greg Kroah-Hartman]

From: Masashi Honma <masashi.honma@xxxxxxxxx>

commit 5024f21c159f8c1668f581fff37140741c0b1ba9 upstream.

kernel test robot says:
drivers/net/wireless/ath/ath9k/htc_drv_txrx.c:987:20: sparse: warning: incorrect type in assignment (different base types)
drivers/net/wireless/ath/ath9k/htc_drv_txrx.c:987:20: sparse:    expected restricted __be16 [usertype] rs_datalen
drivers/net/wireless/ath/ath9k/htc_drv_txrx.c:987:20: sparse:    got unsigned short [usertype]
drivers/net/wireless/ath/ath9k/htc_drv_txrx.c:988:13: sparse: warning: restricted __be16 degrades to integer
drivers/net/wireless/ath/ath9k/htc_drv_txrx.c:1001:13: sparse: warning: restricted __be16 degrades to integer

Indeed rs_datalen has host byte order, so modify it's own type.
