bgpd: backpressure - fix evpn route sync to zebra

In scaled EVPN + ipv4/ipv6 uni route sync to zebra,
some of the ipv4/ipv6 routes skipped reinstallation
due to incorrect local variable's stale value.

Once the local variable value reset in each loop
iteration all skipped routes synced to zebra properly.

Ticket: #3948828
