[PATCH] wifi: ath9k: Use swap() to improve ath9k_hw_get_nf_hist_mid()

[Thorsten Blum]

Use the swap() macro to simplify the ath9k_hw_get_nf_hist_mid() function
and improve its readability.

Fixes the following Coccinelle/coccicheck warning reported by
swap.cocci:

  WARNING opportunity for swap()

Compile-tested only.
