net: stmmac: use netif_tx_start|stop_all_queues() function

Browse Source 
[ Upstream commit 9f19306d16 ]

The current implementation of stmmac_stop_all_queues() and
stmmac_start_all_queues() will not work correctly when the value of
tx_queues_to_use is changed through ethtool -L DEVNAME rx N tx M command.

Also, netif_tx_start|stop_all_queues() are only needed in driver open()
and close() only.

Fixes: c22a3f48 net: stmmac: adding multiple napi mechanism
