[PATCH 05/10] net: icmp: don't overrun buffer on send

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

len is the size of the ICMP echo request and the ICMP echo response will
have the exact same size, but the code erroneously, copied ETHER_HDR_SIZE
bytes worth of extra data beyond the buffer and sent that out.

Fix this by using the correct length.
