btrfs-progs: Fix wrong return value of wait_for_subvolume_cleaning()

Browse Source 
Reproduce:
 # btrfs subvolume sync /mnt/btrfs
 Subvolume id 323 is gone
 # echo $?
 1
 #

Reason:
 wait_for_subvolume_cleaning() return !0 in right case, because
 value of ret is set to "is subvolume clean" state before return.
