packet: reset network header if packet shorter than ll reserved space
[ Upstream commit 993675a3100b16a4c80dfd70cbcde8ea7127b31d ]
If variable length link layer headers result in a packet shorter
than dev->hard_header_len, reset the network header offset. Else
skb->mac_len may exceed skb->len after skb_mac_reset_len.
packet_sendmsg_spkt already has similar logic.
Fixes: b84bbaf7a6c8 ("packet: in packet_snd start writing at link layer allocation")
