commit 960a3166aed015887cd54423a6589ae4d0b65bd5 upstream
Now that we use a dedicated block group and regular writes for data
relocation, we can preallocate the space needed for a relocated inode,
just like we do in regular mode.
Essentially this reverts commit 32430c614844 ("btrfs: zoned: enable
relocation on a zoned filesystem") as it is not needed anymore.
