if_clone.c allows creating multiple interfaces with the same name

[Daan Vreeken]

Hi All,

Recently I've discovered a bug in if_clone.c and if.c where the code allows 
multiple interfaces to be created with exactly the same name (which leads to 
all sorts of other interesting problems).
I've submitted a PR about this with patches, which can be found here :

Could anyone take a look at it?
