Subject: [PATCH 5.12 536/677] mt76: mt7663: fix when beacon filter is being applied

From: Sean Wang <sean.wang@...iatek.com>

[ Upstream commit 4bec61d9fb9629c21e60cd24a97235ea1f6020ec ]

HW beacon filter command is being applied until we're in associated state
because the command would rely on the associated access point's beacon
interval and DTIM information.
