  memblock: exclude NOMAP regions from kmemleak (2021-10-13 08:36:59 +0300)

----------------------------------------------------------------
memblock: fix handling of NOMAP regions with kmemleak.

NOMAP regions don't have linear map entries so an attempt to scan these
areas in kmemleak would fault.

Prevent such faults by excluding NOMAP regions from kmemleak.
