BUILD: ssl_ckch: Fix build error about a possible uninitialized value

A build error is reported about the path variable in the switch statement on
the commit type, in cli_io_handler_commit_cafile_crlfile() function. The
enum contains only 2 values, but a default clause has been added to return an
error to make GCC happy.

This patch must be backported as far as 2.5.
