[ Upstream commit 686cff3d7022ddf35d7e38bc80191eb92de5989a ]

netif_set_real_num_tx_queues() & netif_set_real_num_rx_queues() should be
used to inform network stack about the real Tx & Rx queue (active) number
in both stmmac_open() and stmmac_resume(), therefore, we move the code
from stmmac_dvr_probe() to stmmac_hw_setup().

Fixes: c02b7a914551 net: stmmac: use netif_set_real_num_{rx,tx}_queues
