receive: protect against impossible conditions
It should never be the case that skb->head + skb->transport_header -
skb->data is greater than 2^16, but in case the kernel network stack
borks this at some point in the future, we don't want this to slyly
introduce a vulnerability into WireGuard.
Further, really smart compilers might be able to make deductions about
data_offset, and optimize accordingly.
