[PATCH BlueZ 3/4] shared/gatt-client: Fix bogus asserts

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

The asserts involving notify_count were bogus because it should be
possible to disable a notification even before the remote respond to
the write command.
