BUG/MINOR: ssl/cli: don't overwrite the filters variable

When a crt-list line using an already used ckch_store does not contain
filters, it will overwrite the ckchs->filters variable with 0.
This problem will generate all sni_ctx of this ckch_store without
filters. Filters generation mustn't be allowed in any case.

Must be backported in 2.1.
