nvdimm(4): Calculate and save memattr once; it never changes

Refactor nvdimm_spa_memattr() routine and callers to just save the value at
initialization and use the value directly.  The reference value from NFIT,
MemoryMapping, is read only once, so the associated memattr could never
change.

No functional change.
