qcacld-3.0: fix reassociation issue

While getting reassociation request frame, user space hostapd will
trigger diassociate with reason code 13. Association can't be
established.

The root cause is host driver forwards more 6 bytes to user space.
The 6 bytes is current AP address in association request frame.
Hostapd can't paras association request frame because the additional
6 bytes.

Skip current AP address before forwarding reassociation request
frame to user space.
