libblkid: Add error checking to devicemapper code to avoid segfaults

If a device mapper volume disappears while libblkid code is running,
it is possible for the devicemapper code to return errors, and since
libblkid wasn't checking for error returns, it would dereference a
null pointer and crash.  Add error checking to prevent this.
