[ Upstream commit baaa7ebf25c78c5cb712fac16b7f549100beddd3 ]
This reserved space isn't committed yet but cannot be used for
allocations. For userspace it has no difference from used space.
See the same fix in ext4 commit f06925c73942 ("ext4: report delalloc
reserve as non-free in statfs for project quota").
Fixes: ddc34e328d06 ("f2fs: introduce f2fs_statfs_project")
