Christophe Leroy d80ae83f1f powerpc/ptdump: Fix W+X verification 
Verification cannot rely on simple bit checking because on some
platforms PAGE_RW is 0, checking that a page is not W means
checking that PAGE_RO is set instead of checking that PAGE_RW
is not set.

Use pte helpers instead of checking bits.

Fixes: 453d87f6a8 ("powerpc/mm: Warn if W+X pages found on boot")
