The old behavior before commit d88d7ea0d0be ("batman-adv: bla: avoid CRC
corruption due to parallel claim add") was to only update the
backbone_gw->lasttime when the backbone_gw of the claim changed. But afte
the CRC fix, the backbone_gw->lasttime was updated for each handled claim.
Return back to the old behavior and only update it when the backbone_gw was
changed.

claim add")
