     restores the behavior of this variable to match the "legacy" SSI parser.

https://www.openssl.org/docs/fips/ - using FIPS_mode_set(1) for revalidation
was actually expressly called out in section 3. While mod_ssl is 'unloaded'
(unconfigured) the process is not operating in a fips validated manner, but
once the configuration resets FIPS_mode_set(1) it resumes validated behavior.
