bgpd: fix updating redist bitmask when vrf_id changes

Browse Source 
Problem reported that when "systemctl restart networking" was
performed, prefixes previously redistributed into bgp from connected
were deleted from the bgp table.  Determined that we were not correctly
changing the redistribution bitmask when the vrf_id of the vrf was
changed. This patch corrects that behavior.

Manual tests look good. bgp-min and vrf-min completed with no new failures.
