util/disk_cache: fix size subtraction on 32bit
Negating size_t on 32bit produces a 32bit result. This was effectively adding values close to UINT_MAX to the cache size (the files are usually small) instead of intended subtraction. Fixes 'make check' disk_cache failures on 32bit. Signed-off-by: Grazvydas Ignotas <[email protected]> Reviewed-by: Timothy Arceri <[email protected]>
