Subject: [PATCH] Fix arc_adjust_meta_balanced()

The type of "adjustmnt" was erroneously changed to unsigned when the compressed
ARC code was ported in d3c2ae1c0806b183a315e3d43cc8018cfdca79b5.

As a result of it being unsigned, the balanced metadata eviction logic
would evict all of the non-metadata.
