xfs: only log freed extents for the current RTG in zoned growfs
Otherwise a power fail or crash during growfs could lead to an
elevated sb_rblocks counter.
Note that the step function is much simpler compared to the classic RT
allocator as zoned RT sections must be aligned to real time group
boundaries.
