fs: Add the __data_racy annotation to backing_dev_info.ra_pages
Some but not all .ra_pages changes happen while block layer I/O is paused
with blk_mq_freeze_queue(). Filesystems may read .ra_pages even while
block layer I/O is paused, e.g. from inside their .fadvise callback.
Annotating all .ra_pages reads with READ_ONCE() would be cumbersome.
Hence, add the __data_racy annotatation to the .ra_pages member
variable.
