Fix QAT allocation failure return value
When qat_compress() fails to allocate the required contiguous memory it mistakenly returns success. This prevents the fallback software compression from taking over and (un)compressing the block. Resolve the issue by correctly setting the local 'status' variable on all exit paths. Furthermore, initialize it to CPA_STATUS_FAIL to ensure qat_compress() always fails safe to guard against any similar bugs in the future.
