BUG/MINOR: ssl/cli: fix "show ssl crl-file" not to mix cli+ssl contexts

The "show ssl crl-file" command mixes some generic pointers from the
"ctx.cli" struct with context-specific ones from "ctx.ssl" while both
are in a union. It's fortunate that the p1 pointer in use is located
before the first one used (it overlaps with old_cafile_entry). But
should these fields be reordered or slightly updated this will break.

This needs to be backported to 2.5.
