The last_migrate_reason field uses -1 as a sentinel value to mean "no migration has happened". Replace the four bare -1 occurrences by adding a proper MR_NEVER member to enum migrate_reason, defining a corresponding "never_migrated" string in the MIGRATE_REASON trace macro, and updating the GDB page_owner script to use MR_NEVER instead of the hardcoded -1 so that lx-dump-page-owner does not incorrectly report unmigrated pages as migrated. No functional change.
