If updating the dm device in the kernel fails we cannot leave
the mpp size updated, because if we correct the problem and
try to resize later multipathd prevents resizing the device
of the size has not changed.
I hit this when all paths to a dm-multipath device where not
yet updated but multipathd resize was run.
