Cirrus: workaround root expand failure

Occasionally, and seemingly only on F29 the root disk fails to expand
upon boot.  When this happens, any number of failures could occur if
space runs out.  Until there is time to investigate the actual cause,
workaround this problem by detecting it and acting accordingly.
