dm: eliminate potential source of excessive kernel log noise
There wasn't ever a real need to log an error in the kernel log for ioctls issued with insufficient permissions. Simply return an error and if an admin/user is sufficiently motivated they can enable DM's dynamic debugging to see an explanation for why the ioctls were disallowed. Reported-by:Nir Soffer <nsoffer@redhat.com> Fixes: e980f623 ("dm: don't allow ioctls to targets that don't map to whole devices") Signed-off-by:
