zebra: fix interface deletion bug introduced by ptp address support

Browse Source 
meh. forgot to even look at the interface deletion path. this doesn't
really work well when looking for the local address in the subnet list
which has the connected prefix in it... loop ensues.

fix by using the connected prefix when looking at the list of connected
prefixes. duh.
