NetRxPkt: Fix memory corruption on VLAN header stripping
This patch fixed a problem that was introduced in commit eb700029.
When net_rx_pkt_attach_iovec() calls eth_strip_vlan()
this can result in pkt->ehdr_buf being overflowed, because
ehdr_buf is only sizeof(struct eth_header) bytes large
but eth_strip_vlan() can write
sizeof(struct eth_header) + sizeof(struct vlan_header)
bytes into it.
Devices affected by this problem: vmxnet3.
