If Gnss Measurements callback is called at the same time as Gnss Measurements close is called, this will cause dead lock. Remove using mutex in this case and instead use a simple bool to know whether or not to call into a the callback. Bug: 63909793 Change-Id: I98d2be5ebd2ee0f36e4d2e31d20a74585089fe31 CRs-fixed: 2089716
