f2fs: fix to check available space of CP area correctly in update_ckpt_flags()
Otherwise, nat_bit area may be persisted across boundary of CP area during nat_bit rebuilding. Fixes: 94c821fb286b ("f2fs: rebuild nat_bits during umount") Signed-off-by: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
