dyndbg: unwrap __ddebug_add_module inner function NOTYET

The inner func has a base arg which is unused in the body, so theres
no point in having the inner fn.

Its one-time purpose was to expose a wider interface to the internal
caller: dynamic_debug_init(), to allow communicating each module's
offset in the builtin _ddebug[] table.

That purpose was obsoleted by cited commit, when ddebug_add_module()
was converted to pass a *ddebug_info, which is used as a cursor by the
caller.

TODO: the cited commit gives another reason for base, to provide an
index in support of de-duplicating column data.  Refresh that patchset
to see if its still true.

Fixes: b7b4eeb ("dyndbg: gather __dyndbg[] state into struct _ddebug_info")
