Bluetooth: mgmt: Fix count parameter in get_connections reply
This patch fixes the count parameter in the Get Connections reply message. We cannot know the right number until iterating through all connections so set the parameter value only after the loop. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Acked-by: Marcel Holtmann <marcel@holtmann.org>
