ip6_tunnel: fix error code when tunnel exists
After commit 2b0bb01b6edb, the kernel returns -ENOBUFS when user tries to add
an existing tunnel with ioctl API:
$ ip -6 tunnel add ip6tnl1 mode ip6ip6 dev eth1
add tunnel "ip6tnl0" failed: No buffer space available
It's confusing, the right error is EEXIST.
This patch also change a bit the code returned:
- ENOBUFS -> ENOMEM
- ENOENT -> ENODEV
Fixes: 2b0bb01b6edb ("ip6_tunnel: Return an error when adding an existing tunnel.")
