FS#1206 - ath kernel oops on boot

Supply the following if possible:
- Device problem occurs on :
Meraki MR18
- Software versions of LEDE release, packages, etc.
Standard 17.01.4.
- Steps to reproduce
This is happening on a Meraki MR18, bootstrapped using @riptidewave93s bringup method described at https://medium.com/openwrt-iot/lede-openwrt-installing-firmware-on-meraki-mr18-e96e4e081710. It was then sysupgraded to 17.01, and then 17.01.4 when appropriate.

Following a LEDE factory reset in order to wipe the configuration, it is now seemingly unable to bring up 2 of the 3 radio interfaces. The following output has been observed in dmesg, where it seems that the ath module is causing a kernel oops.

My other MR18 with LEDE 17.04.1 has not been reset in this manner, and continues to work, and does not exhibit the kernel oops on boot.

‘iw phy’ lists all 3 radios, whereas ‘iw dev’ lists only wlan2.
