[PATCH] network: query signal strength when status changes to registered or roaming.

From: Marit Henriksen <marit.henriksen@stericsson.com>

Signal strength is set to -1 whenever registration status changes
and differs from registered or roaming. When registration status
changes again to registered or roaming, the signal strength needs to
be updated, so add query towards driver to get it.
