Yup, reinstalling the kmod-ath10k package (or just copying over the new
.ko) and rmmod/insmod is fine. Just make sure you get all the modules
(including all the ath* and mac80211*).

LEDE backports the entire WiFi stack. So it's way newer than the rest of
the kernel; think you can see the date it was backported in the version
number in the Makefile.
