BUG/MEDIUM: 51d: fix possible segfault on deinit_51degrees()

When haproxy is built with 51Degrees support, but not configured to use
51Degrees database, a segfault can occur when deinit_51degrees()
function is called, eg. during soft-stop on SIGUSR1 signal.

Only builds that use Pattern algorithm are affected.

This fix must be backported to all stable branches where 51Degrees
support is available. Additional adjustments are required for some
branches due to API and naming changes.
