Revert memory change for c0101 c0102
c0101 and c0102 (out of warranty) previously lost a stick of memory (i.e. not visible to the OS). These nodes have since reverted back to having all 256G visible.
This change reverts the previous change to nhc.conf so that the check_hw_physmem is now 256gb like the other P100 nodes (c0097 .. 114)
