[committed] Handle low-mem die-limit >= max die-limit

[Tom de Vries <tdevries@suse.de>]

Hi,

Specifying a low-mem die-limit that is larger than or equal to the
max die-limit has the effect of disabling low-mem mode.  Make this
explicit by setting it to the 'none' value.

Committed to trunk.

Thanks,
- Tom
