[PATCH net-next v2] vxlan: Remove unnecessary comments for vxlan_rcv() and vxlan_err_lookup()

Remove the two unnecessary comments around vxlan_rcv() and
vxlan_err_lookup(), which indicate that the callers are from
net/ipv{4,6}/udp.c. These callers are trivial to find. Additionally, the
comment for vxlan_rcv() missed that the caller could also be from
net/ipv6/udp.c.
