mm: convert core mm 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.
This will result in the debug output being that of a bitmap output, which
will result in a minor change here, but since this is for debug only, this
should have no bearing.
Otherwise, no functional changes intended.
