ar71xx: ag71xx: preserve port mirror flags during swconfig apply
The swconfig load operation always triggers 'apply' function which in this driver currently clears port mirroring flags effectively undoing port mirroring configuration. This fix preserves port mirroring flags during apply. Signed-off-by: Milan Krstic <milan.krstic@gmail.com>
