mm: migrate: provide buffer_migrate_page_norefs()
Provide a variant of buffer_migrate_page() that also checks whether there
are no unexpected references to buffer heads. This function will then be
safe to use for block device pages.
[akpm@linux-foundation.org: remove EXPORT_SYMBOL(buffer_migrate_page_norefs)]
