wlan: Fix SAP TX QOS prioritization

As part of Soft AP flow control implementation to get the station
and access category to fetch packets from corresponding queue weight
is not decremented. This impacts the QOS prioritization on when SAP
interface is up. In this change decrement the access category weight
when a packet is fetched from it's queue.
