wifi: mt76: mt7925: pass mlink to set_link_key()

Browse Source 
Drop the mt792x_sta_to_link() lookup in mt7925_set_link_key() and pass
the resolved mlink from the caller instead. The link context is already
known at the call site, making the lookup redundant.

This keeps the helper lookup-free and makes link ownership explicit.

No functional change intended.
