Btrfs: fix inode cache writeout

Browse source

The code to fix stalls during free spache cache IO wasn't using
the correct root when waiting on the IO for inode caches.  This
is only a problem when the inode cache is enabled with

mount -o inode_cache

This fixes the inode cache writeout to preserve any error values and
makes sure not to override the root when inode cache writeout is done.
