xfs: factor rmap btree size into the indlen calculations commit fd26a88093bab6529ea2de819114ca92dbd1d71d upstream. When we're estimating the amount of space it's going to take to satisfy a delalloc reservation, we need to include the space that we might need to grow the rmapbt. This helps us to avoid running out of space later when _iomap_write_allocate needs more space than we reserved. Eryu Guan observed this happening on generic/224 when sunit/swidth were set.
