lib: fix segfault on exit caused by interface removal

Browse Source 
Add missing bits to properly unlink interface in the if_unlink_per_ns()
function.

In the long term we should convert if_table to use a more convenient
data structure like a red-black tree instead of a routing table.

Fixes issue #398.
