Btrfs: fix FS_IOC_SETFLAGS ioctl
Steps to reproduce the bug: - Call FS_IOC_SETLFAGS ioctl with flags=FS_COMPR_FL - Call FS_IOC_SETFLAGS ioctl with flags=0 - Call FS_IOC_GETFLAGS ioctl, and you'll see FS_COMPR_FL is still set! Signed-off-by: Li Zefan <lizf@cn.fujitsu.com> Signed-off-by: Chris Mason <chris.mason@oracle.com>
