[PATCH BlueZ] client: Avoid scan prompt when discovery is already active

[z4pdyy@gmail.com]

From: z4pdy <305461556+z4pdy@users.noreply.github.com>

Check the adapter's Discovering property before prompting the user
to start scanning. This avoids prompting to scan when discovery is
already in progress, which previously resulted
in an org.bluez.Error.InProgress error.
