btrfs: use the folio iterator in btrfs_end_super_write()

Browse source

Iterate over folios instead of bvecs.  Switch the order of unlock and put
to be the usual order; we know this folio can't be put until it's been
waited for, but that's fragile.  Remove the calls to ClearPageUptodate /
SetPageUptodate -- if PAGE_SIZE is larger than BTRFS_SUPER_INFO_SIZE,
we'd be marking the entire folio uptodate without having actually
initialised all the bytes in the page.
