xfs: recompute growfsrtfree transaction reservation while growing rt volume
While playing with growfs to create a 20TB realtime section on a
filesystem that didn't previously have an rt section, I noticed that
growfs would occasionally shut down the log due to a transaction
reservation overflow.
xfs_calc_growrtfree_reservation uses the current size of the realtime
summary file (m_rsumsize) to compute the transaction reservation for a
growrtfree transaction. The reservations are computed at mount time,
which means that m_rsumsize is zero when growfs starts "freeing" the new
realtime extents into the rt volume. As a result, the transaction is
undersized and fails.
Fix this by recomputing the transaction reservations every time we
change m_rsumsize.
