[IOS-XE] ShowBgpNeighborsAdvertisedRoutesSuperParser broken if no device connection exists

[gramik151]

When trying to use 'ShowBgpNeighborsAdvertisedRoutesSuperParser' in iosxe/show_bgp.py, but without an active 'device' object (i.e., passing CLI output obtained elsewhere), the code fails. I believe the section starting on line 4327 needs to be indented one level, so that the attempt to learn the VRF is only done if 'vrf' does not exist / is not passed as an argument.

By moving lines 4327 through 4345 underneath the if block, and passing vrf='default', the code works for me.
