`cert_store_path` is not be used in (fInCert || blob) branch. This commit moves the previously added free(cert_store_path) to the front of the branch, so that we do not need to do it on the subsequent three error paths under the branch.

cert_store_pathis allocated viaget_cert_location()aftercert_pathis allocated.This PR fixes the potential memory leak of cert_store_path on four (original) error paths.
Overall, three of the four error paths are under the branch if(fInCert || blob) {...) and it is not actually used in the branch, so I just free it at the beginning of the branch along with
curlx_unicodefree(cert_path);.
