3.11.10.9 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Felix Fietkau <nbd@openwrt.org>

commit 764152ff66f4a8be1f9d7981e542ffdaa5bd7aff upstream.

Their power value is initialized to zero. This patch fixes an issue
where the configured power drops to the minimum value when AP_VLAN
interfaces are created/removed.
