Follow up for creating parent dir for config files

The commit Ia5fcfe6c63f5cc40b11f7e1f3be244d7897f26f6 wanted to enable
config file creation even if its parent dir not exists. But missed that
the caller of merge_config_file, merge_config_group already checks for
hte missing directory. So creating the missing dir in merge_config_file
is too late.

This patch moves the dir creation to the caller.
