Florian Westphal f468c48d48 netfilter: xt_physdev: masks are not c-strings 
... and must not be subjected to the 'nul terminated' constraint.
If the interface name is 15 characters long, the mask is 16-bytes
'0xff' (to cover for \0) and the valid device name is rejected.

Fixes: 8df772afc9 ("netfilter: x_physdev: reject empty or not-nul terminated device names")
Cc: stable@vger.kernel.org
Closes: https://bugs.launchpad.net/neutron/+bug/2159935
