xfs: fix unit conversions in per_binval computation

LOLLM noticed that we’re doing the unit conversion in the per_binval
computation backwards — xfs_buf_inval_log_space’s second parameter is
supposed to be in bytes, but max_binval is in units of fsblocks. Hence
the conversion should be FSB -> B, not the other way around.
