This code is a bit weird. We would return an error, then mt7601u_dma_init() will call mt7601u_free_tx_queue() which doesn't check for tx_q == NULL condition. Looks like mt7601u_free_tx() has to check for dev->tx_q == NULL and return early if that's the case. Or mt7601u_alloc_tx() should really clean things up on it's own on failure. Ugh.
