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.
