Merge branch 'vxlan-rx-cleanups'

Jiri Benc says:

====================
vxlan: consolidate rx handling

Currently, vxlan_rcv is just called at the end of vxlan_udp_encap_recv,
continuing the rx processing where vxlan_udp_encap_recv left it. There's no
clear border between those two functions. This patchset moves
vxlan_udp_encap_recv and vxlan_rcv into a single function.

This also allows to do some simplification in error path.

The VXLAN-GPE implementation that will follow up this set can be seen at:
