Subject: [PATCH] mt76x02: fix client mode authentication by supporting all 16
 BSSID slots

Change the BSSID index mask from 7 to 0xf in mt76x02_mac_set_bssid()
to properly support all 16 hardware BSSID slots (0-15).

The hardware is configured for "8 APs + 8 STAs" mode where:
- Indices 0-7 are used for AP mode
- Indices 8-15 are used for client (STA) mode

The previous mask of 7 (0b0111) was truncating client mode indices
8-15 back to 0-7, causing client interfaces to write their BSSID to
the wrong hardware register. This resulted in the hardware not
recognizing the AP's BSSID during authentication, leading to
authentication timeouts.

Fixes authentication timeout issue when mt7612/mt7662 operates in
client mode.
