Dan Williams 0a370d261c libnvdimm, pmem: clarify the write+clear_poison+write flow
The ACPI specification does not specify the state of data after a clear
poison operation.  Potential future libnvdimm bus implementations for
other architectures also might not specify or disagree on the state of
data after clear poison.  Clarify why we write twice.
