tune2fs: fix quota feature removal

When the last quota inode is removed, the 'quota' feature
flag was not removed from superblock in some cases.
Ex:
$ mke2fs -t ext4 -O quota <dev>  # creates both usr & grp
                                  # quota inodes
$ tune2fs -Q ^usrquota <dev>  # removes usr quota inode
$ tune2fs -Q ^grpquota <dev>  # removes grp quota inode,
                               # but the 'quota' feature flag
                               # was not removed from superblock
This patch removes the 'quota' feature flag from superblock
if none of the quota inodes are set.
