I would like to change ifc_destroy to return an int, so it can give the
user an error message when ifconfig dev destroy fails for some reason.

Places where this would be useful:

if_loop: return EPERM when trying to destroy lo0.
if_sl/if_strip (not cloning yet): return EBUSY when device is open.
if_tun: return EBUSY when device is open (maybe..? reduces lot of complexity).

Are there any objections to making this change?
