When an LE connection request is made, advertising is disabled and never resumed. When a client has an active advertisement, this is disruptive. This change adds resume logic for client-configured (non-directed) advertisements after the connection attempt. The patch was tested by registering an advertisement, initiating an LE connection from a remote peer, and verifying that the advertisement is re-activated after the connection is established. This is performed on Hatch and Kukui Chromebooks.
