[ Upstream commit 709ec3f7fc5773ac4aa6fb22c3f0ac8103c674db ]

In QMI new server notification we enable the NGD however during
delete server notification we do not disable the NGD.

This can lead to multiple instances of NGD being enabled, so make
sure that we disable NGD in delete server callback to fix this issue!
