mm: convert arch-specific code to mm_flags_*() accessors

As part of the effort to move to mm->flags becoming a bitmap field,
convert existing users to making use of the mm_flags_*() accessors which
will, when the conversion is complete, be the only means of accessing
mm_struct flags.

No functional change intended.
