  tls_wolfssl: fix regression in commit 77f5f5a

The wolfSSL_CTX_load_verify_locations_ex() function would still return
an error when no valid CA certificate was found in the directory.
Since before commit 77f5f5a, opensips startup would not fail when
wolfSSL_CTX_load_verify_locations_ex() would return an error, the change
in the above commit would constitute a regression for cases where no valid
certificate is found in the directory.

This commit brings the wolfssl behavior further in line with openssl.
