mt76: fix possible NULL pointer dereference in mt76_tx

[ Upstream commit d7400a2f3e295b8cee692c7a66e10f60015a3c37 ]

Even if this is not a real issue since mt76_tx is never run with wcid set
to NULL, fix a theoretical NULL pointer dereference in mt76_tx routine

Fixes: db9f11d3433f7 ("mt76: store wcid tx rate info in one u32 reduce locking")
