libxenlight: fix segfault when domid_to_name returns NULL
The function libxl_domid_to_name() can return NULL if the path
/local/domain/%d/name does not exist. This causes a segfault if the
NULL name is later passed as a value to libxl_xs_writev(). I'm
hitting this making a call to libxl_device_vfb_add() from my graphical
switcher application.
This patch modifies xs_writev() and libxl_xs_writev() to skip NULL
values.
