ENGR00286017: net:fec: fix clock enable/disable usecount mismatch

Reproduce:
1. Boot up kernel with DHCP;
2. ifconfig eth0 down;
3. echo mem > /sys/power/state;

There have clock enable/disable usecount mismatch warning dump.

Fix this by checking device's netif_running state is up and then
enable/disable clock.
