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. Addresses-RedHat-Bugzilla: #433857 Signed-off-by: Eric Sandeen <sandeen@redhat.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
