BUG/MINOR: ssl/cli: fix a potential NULL dereference

Fix a potential NULL dereference in "show ssl cert" when we can't
allocate the <out> trash buffer.

This patch creates a new label so we could jump without trying to do the
ci_putchk in this case.

This bug was introduced by ea987ed ("MINOR: ssl/cli: 'new ssl cert'
command"). 2.2 only.

This bug was referenced by issue #556.
