bgpd: Fix for local interface MAC cache issue in 'bgp mac hash' table
Issue:
During FRR restart, we fail to add some of the local interface's MAC
to the 'bgp mac hash'. Not having local MAC in the hash table can cause
lookup issues while receiving EVPN RT-2.
Currently, we have code to add local MAC(bgp_mac_add_mac_entry) while handling
interface add/up events in BGP(bgp_ifp_up/bgp_ifp_create). But the code
'bgp_mac_add_mac_entry' in bgp_ifp_create is not getting invoked as it
is placed under a specific check(vrf->bgp link check).
Fix:
We can skip this check 'vrf->bgp link existence' as the tenant VRF might
not have BGP instance but still we want to cache the tenant VRF local
MACs. So keeping this check in bgp_ifp_create inline with bgp_ifp_up.
