lib : fix duplicate prefix list delete

Problem statement:
Step-1:
pl1 - 10.10.10.10/24 with deny sequence 1
Step-2:
pl1 - 10.10.10.10/24 with permit sequence 2
Step-3:
pl1 - 20.20.20.20/24 with deny sequence 1

Now we end up deleting permit sequence 2,
which might blackhole the traffic.

RCA:
Whenever we have multiple prefix lists,
having same prefix and different subnet range,
delete or replace of prefix list
would result in delete of entry in route-map
prefix table.

Fix:
We will skip deleting prefix list entry
from routemap prefix table, if we have
the multiple prefix lists having same prefix.
