Subject: [PATCH] [previewjob] Check whether thumbRootDevice is valid before
 access

storageAccessFromPath may return an invalid device, e.g. because the thumbnail directory doesn't exist yet

In that case we must not use the device

BUG: 470845
(cherry picked from commit 3fdcb7bcdae3a3dc95ce5b3d15740802450b129e)
