bgpd: remove unnecessary checkings for bgp_evpn_es_new()

Browse Source 
Currently, `bgp_evpn_es_new()` always has an invald `struct bgp` pointer as
its input parameter, and it will always return valid `es`.

So two cleanup changes:
- Remove unnecessary checking for `bgp` in `bgp_evpn_es_new()`
- Remove unnecessary checkings of `bgp_evpn_es_new()`'s callers.
