btrfs: return ptr error from compression workspace
The btrfs compression wrappers translated errors from workspace allocation to either -ENOMEM or -1. The compression type workspace allocators are already returning a ERR_PTR(-ENOMEM). Just return that and get rid of the magical -1. This helps a future patch return errors from the compression wrappers. Signed-off-by:Zach Brown <zab@redhat.com> Reviewed-by:
