GRO_LEGACY_MAX_SIZE = 65536; total_len being 65536 is too big to fit
into a u16. As can be seen in skb_gro_receive, packets bigger or equal
to gro_max_size (or GRO_LEGACY_MAX_SIZE) are dropped with -E2BIG. Apply
the same boundary to geneve_post_decap_hint to avoid writing 65536 to a
16-bit iph->tot_len field with an overflow.
Fixes: fd0dd79657 ("geneve: use GRO hint option in the RX path")
