Subject: [PATCH 2/2]: acpica/nfit: Rename not-armed bit definition

ACPI 6.0 NFIT Memory Device State Flags in Table 5-129 defines
bit 3 as follows.

  Bit [3] set to 1 to indicate that the Memory Device is observed
  to be not armed prior to OSPM hand off. A Memory Device is
  considered armed if it is able to accept persistent writes.

This bit is currently defined as ACPI_NFIT_MEM_ARMED, which can be
confusing as if the Memory Device is armed when this bit is set.

Change the name to ACPI_NFIT_MEM_NOT_ARMED per the spec.
