wifi: mt76: mt7915: Fix an error handling path in mt7915_add_interface()

Browse Source 
If mt76_wcid_alloc() fails, the "mt76.mutex" mutex needs to be released as
done in the other error handling paths of mt7915_add_interface().

Fixes: f3049b88b2 ("wifi: mt76: mt7915: allocate vif wcid in the same range as stations")
