acl_create_le_connection_with_id -> create_le_connection

create_le_connection is adding device directly to AclManager, and relying on it's "direct
connect" implementation.
direct_connect_add method is doing multiplexing of apps request, and
sending the request to AclManager, but it lacks some extra checks and lookups.

Currently these methods are exclusive, if you try to use both you will
get some bad behavior. These should be merged into one.

This patch is moving both methods into same location, so it's easier to
merge them into one under a flag.
