Btrfs: fix page->private races
There is a race where btrfs_releasepage can drop the
page->private contents just as alloc_extent_buffer is setting
up pages for metadata. Because of how the Btrfs page flags work,
this results in us skipping the crc on the page during IO.
This patch sovles the race by waiting until after the extent buffer
is inserted into the radix tree before it sets page private.
