xfs: report "max_resp" used for min log size computation
Move the tracepoint that computes the size of the transaction used to
compute the minimum log size into xfs_log_get_max_trans_res so that we
only have to compute this stuff once.
Leave xfs_log_get_max_trans_res as a non-static function so that xfs_db
can call it to report the results of the userspace computation of the
same value to diagnose mkfs/kernel misinteractions.
