test: dm: hash: check digest size before memset

hash_algo_digest_size() returns -EINVAL for an invalid algorithm. The
test success provider passes that result directly to memset(), where it
is converted to a large size_t.

Return the error before touching the output buffer, and exercise the
invalid-algorithm path in the provider-selection test. This addresses
Coverity CIDs 652907 and 652908.
