Lorenzo Stoakes 96c09ae60b mm: prefer mm->def_vma_flags in mm logic ...

Currently mm->def_flags (of type vm_flags_t) is union'd with
mm->def_vma_flags (of type vma_flags_t).

As part of the effort to convert vm_flags_t usage to vma_flags_t (in order
to no longer be arbitrarily limited to a system word size for VMA flags),
prefer mm->def_vma_flags to mm->def_flags throughout the mm logic.

We update dump_mm() to use the %*pb format which means we make no
assumption about the number of VMA flag bits on output when outputting
default VMA flags.

No functional change intended.
