btrfs-progs: judge the return value of check_mounted more accurately
For btrfs-convert, btrfstune, btrfs rescue, they report "device busy" when given a device that does not actually exist e.g. # btrfstune -x abcdefg (this device does not exist) $ ...device busy... We deal with this case by add "ret < 0" error check when judging the return value of check_mounted.
