wifi: mt76: mt7925: add mt7925_mac_link_bss_remove to remove per-link BSS

The mt7925_mac_link_bss_remove function currently removes the per-link BSS.
We will extend this function when we implement the MLO functionality.

This patch only includes structural changes and does not involve any
logic changes.
