gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-28) complains:
xenctrl_stubs.c: In function 'stub_xc_domain_create':
xenctrl_stubs.c:216:28: error: 'val' may be used uninitialized
in this function [-Werror=maybe-uninitialized]

xenctrl_stubs.c:198:12: error: 'val' may be used uninitialized

cc1: all warnings being treated as errors
GCC doesn't point at the correct piece of code, but the diagnostic text is
correct, and can occur when the list is empty. Initialise val to 0.
