Rvert "Register for Service Changed notifications for untrusted devices"

This reverts commit 05fa852c.

Instead of reusing service discovery data, gatt profile initiates
discovery by service uuid before regular service discovery is started,
and both discovery procedures interfere with each other.
As a result, link is dropped.
