[OpenWrt-Devel] [PATCH] base-files: sysupgrade: Bring down wifi just before killall

[Jeff Kletsky]

From: Jeff Kletsky <git-commits at allycomm.com>

Wifi can, in certain situations, cause sysupgrade to fail silently
with a 256 return value as all processes can't be killed.
One of these situations is mesh with batman-adv active.

Added `wifi down` just prior to the killall sequence in stage2

Run-tested-on: Linksys EA8300
