net: mvneta: set rx mode during resume if interface is running
I found a bug by:
0. boot and start dhcp client
1. echo mem > /sys/power/state
2. resume back immediately
3. don't touch dhcp client to renew the lease
4. ping the gateway. No acks
Usually, after step2, the DHCP lease isn't expired, so in theory we
should resume all back. But in fact, it doesn't. It turns out
the rx mode isn't resumed correctly. This patch fixes it by adding
mvneta_set_rx_mode(dev) in the resume hook if interface is running.
