Subject: mm/mremap: start addresses are properly aligned
After previous cleanup, extent is the minimal step for both source and
destination. This means when extent is HPAGE_PMD_SIZE or PMD_SIZE,
old_addr and new_addr are properly aligned too.
Since these two functions are only invoked in move_page_tables, it is safe
to remove the check now.
