[PATCH] btrfs-progs: balance: usage range filter not working

[Illia Bobyr <illia.bobyr@gmail.com>]

When range support was added to the usage filter, a bug was
introduced, as `BTRFS_BALANCE_ARGS_USAGE` is set unconditionally, even
when `BTRFS_BALANCE_ARGS_USAGE_RANGE` is also set.

If `BTRFS_BALANCE_ARGS_USAGE` is set, `BTRFS_BALANCE_ARGS_USAGE_RANGE` is
ignored, see `fs/btrfs/volumes.c:should_balance_chunk()`.
