By delaying freeing the XLU_Config object until the end we miss doing
so on various success and error paths.
Instead free it as soon as the parsing is complete and ensure that
parse errors come through this path by exiting the loop early and
handling that error after the free instead of returning directly from
the loop.
Compile tested only.

v2: Move NULL assignment here from "xl: free config_data on error in
domain_create" where it didn't belong.
v1: Not posted.
