wifi: ath: false-positive fortified-memset warnings

From: Arnd Bergmann <arnd@arndb.de> While testing some other patch series I worked on across gcc versions, I found a couple of stringop warnings that only show up with some toolchains but not others. The warnings I both seem to be false positive. I have also not found an explanation why both of these happen in atheros wireless drivers, as I don't see this in other drivers. Maybe Kees can work out what is going on here.
