wifi: ath6kl: Constify struct cfg80211_ops
'struct cfg80211_ops' is not modified in this driver.
Constifying this structure moves some data to a read-only section, so
increases overall security, especially when the structure holds some
function pointers.
On a x86_64, with allmodconfig, as an example:
Before:
======
text data bss dec hex filename
143726 34579 192 178497 2b941 drivers/net/wireless/ath/ath6kl/cfg80211.o
After:
=====
text data bss dec hex filename
