net: mt7628-eth: free rx descriptor on receiving failure

When received a packet with an invalid length recorded in rx descriptor,
we should free this rx descriptor to allow us to continue to receive
following packets.
Without doing so, u-boot will stuck in a dead loop trying to process this
invalid rx descriptor.

This patch adds a call to mt7628_eth_free_pkt() after received an invalid
packet length.
