net: macb: Use dev_consume_skb_any() to free TX SKBs
The napi_consume_skb() function is not intended to be called in an IRQ
disabled context. However, after commit
6bc8a5098bf4 ("net: macb: Fix
tx_ptr_lock locking"), the freeing of TX SKBs is performed with IRQs
disabled. To resolve the following call trace, use dev_consume_skb_any()
for freeing TX SKBs:
