ath9k: Fix interrupt handling for the AR9002 family
commit 73f0b56a1ff64e7fb6c3a62088804bab93bcedc2 upstream.
This patch adds a driver workaround for a HW issue.
A race condition in the HW results in missing interrupts,
which can be avoided by a read/write with the ISR register.
All chips in the AR9002 series are affected by this bug - AR9003
and above do not have this problem.
