Fix memory leak in libpq when using sslmode=verify-full

Checking if Subject Alternative Names (SANs) from a certificate match
with the hostname connected to leaked memory after each lookup done.

This is broken since acd08d7 that added support for SANs in SSL
certificates, so backpatch down to 9.5.
