mm: fix exports that inadvertently make put_page() EXPORT_SYMBOL_GPL
Commit e76384884344 ("mm: introduce MEMORY_DEVICE_FS_DAX and
CONFIG_DEV_PAGEMAP_OPS") added two EXPORT_SYMBOL_GPL() symbols, but
these symbols are required by the inlined put_page(), thus accidentally
making put_page() a GPL export only. This breaks OpenAFS (at least).
Mark them EXPORT_SYMBOL() instead.
