USB: gadget: u_ether: Change skb->len check for jumbo frames
There is a chance that jumbo frames whose length greater than
EHT_FRAME_LEN(1514) can be sent by host if it is configured for MTU sizes
greater than 1500. Currently driver is checking for skb->len greater than
ETH_FRAME_LEN, which fails in case of jumbo frames received. Hence fix the
issue by changing check for skb->len > GETHER_MAX_ETH_FRAME_LEN in rx_work.
