lib: Keep proper count of prefix-list hit-count when used

When a prefix-list is applied to a BGP neighbor to deny the learning
of specific routes, the hit count is showing 0 for BGP even though
the routes are being filtered correctly due
to the configured prefix-list.

Before fix:

c1# show ip prefix-list nag seq 10
ZEBRA: seq 10 permit any (hit count: 0, refcount: 0)
BGP: seq 10 permit any (hit count: 0, refcount: 0)
c1# show ip prefix-list nag seq 5
ZEBRA: seq 5 deny 1.0.1.0/24 (hit count: 0, refcount: 0)
BGP: seq 5 deny 1.0.1.0/24 (hit count: 0, refcount: 0)

Fix: Increment the prefix-list's hit count whenever a rule match occurs.

After Fix:

c1# show ip prefix-list nag seq 10
ZEBRA: seq 10 permit any (hit count: 0, refcount: 0)
BGP: seq 10 permit any (hit count: 6, refcount: 0)
c1# show ip prefix-list nag seq 5
ZEBRA: seq 5 deny 1.0.1.0/24 (hit count: 0, refcount: 0)
BGP: seq 5 deny 1.0.1.0/24 (hit count: 1, refcount: 0)
