net: airoha: Add size check for TX NAPIs in airoha_qdma_cleanup()
If airoha_qdma_init routine fails before airoha_qdma_tx_irq_init() runs
successfully for all TX NAPIs, airoha_qdma_cleanup() will
unconditionally runs netif_napi_del() on TX NAPIs, triggering a NULL
pointer dereference. Fix the issue relying on q_tx_irq size value to
check if the TX NAPIs is properly initialized in airoha_qdma_cleanup().
Moreover, run netif_napi_add_tx() just if irq_q queue is properly
allocated.
