libxl: fix unitialized variables in libxl__primary_console_find

gcc 4.5 as shipped with openSuSE 11.4 does not recognize the case of
LIBXL_DOMAIN_TYPE_INVALID properly:

cc1: warnings being treated as errors
libxl.c: In function 'libxl_primary_console_exec':
libxl.c:1408:14: error: 'domid' may be used uninitialized in this function
libxl.c:1409:9: error: 'cons_num' may be used uninitialized in this function
libxl.c:1410:24: error: 'type' may be used uninitialized in this function
libxl.c: In function 'libxl_primary_console_get_tty':
libxl.c:1421:14: error: 'domid' may be used uninitialized in this function
libxl.c:1422:9: error: 'cons_num' may be used uninitialized in this function
libxl.c:1423:24: error: 'type' may be used uninitialized in this function
make[3]: *** [libxl.o] Error 1

Fix this by adding a default case.
