net: stmmac: use consistent tests for receive buffer size

Browse Source 
Two out of the three sites that set the receive buffer size (via
stmmac_set_dma_bfsize()) check for rx_q->xsk_pool &&
rx_q->buf_alloc_num. One uses just rx_q->xsk_pool.

Discussing with Yoong Siang Song, the conclusion is that
stmmac_dma_operation_mode() is missing the rx_q->buf_alloc_num
check. Add this check.
