zstd: Check errors right affer compressing/decompressing

David Gouletrequested to merge
dgoulet/tor:ticket40739_047_01 into maint-0.4.7

Considering a compression bomb before looking for errors led to false negative log warnings. Instead, it is possible the work failed for whatever reasons which is not indicative of a compression bomb.

Fixes #40739
