btrfs-progs: subvol sync: fix reversed condition

In my local change to 07cc891d1d9819d5cf0628af555e7727d289cf7b
("btrfs-progs: Simplify all-subvolumn-clean condition for
wait_for_subvolume_cleaning") that reversed the meaning of the variable
dirty -> clean, I made a mistake and broke 'subvol sync' that will not
wait as expected and ends prematurely. Zhao Lei's original patch worked.
