net: mctp: usb: initialise mac header in RX path
We're not currently setting skb->mac_header on ingress, and the netdev
core rx path expects it. Without it, we'll hit a warning on DEBUG_NETDEV
from commit 1e4033b53db4 ("net: skb_reset_mac_len() must check if
mac_header was set")
Initialise the mac_header to refer to the USB transport header.
Fixes: 0791c0327a6e ("net: mctp: Add MCTP USB transport driver")
