Samuel Nevala 787dcd9e4d winrt: Prevent camera device from being suspended.
On certain Lumia devices video buffer gets page locked when camera
is stopped. Subsequent call to video frame map/unmap leads to camera
device suspension. As a fix delay camera unload until all mapped
video frames are unmapped and return early from video frame map when
camera is not active.
