[Xen-devel] [PATCH] libxl: do not call libxl__file_reference_unmap two times

[Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>]

Fix double free due to libxl__file_reference_unmap(&info->kernel) called
multiple times: first at the end of libxl__domain_build and then in
libxl_domain_build_info_destroy.
