mm: add zap_skip_check_mapping() helper
Use the helper for the checks. Rename "check_mapping" into
"zap_mapping" because "check_mapping" looks like a bool but in fact it
stores the mapping itself. When it's set, we check the mapping (it must
be non-NULL). When it's cleared we skip the check, which works like the
old way.
Move the duplicated comments to the helper too.
