hdata/memory: Fix warning message
hdata/memory: Fix warning message

Even though we added memory to device tree, we are getting below warning.

Sample log:
[   57.136949696,3] Unable to use memory range 0 from MSAREA 0
[   57.137049753,3] Unable to use memory range 0 from MSAREA 1
[   57.137152335,3] Unable to use memory range 0 from MSAREA 2
[   57.137251218,3] Unable to use memory range 0 from MSAREA 3

Fixes: 4822a7ba (hdata/memory: Add NVDIMM support)
