[PATCH] contrib/vhost-user-blk: add missing GOptionEntry NULL terminator

[Stefan Hajnoczi]

The GLib documentation says "a NULL-terminated array of GOptionEntrys"
so we'd better make sure there is a terminator that lets
g_option_context_add_main_entries() know when the end of the array has
been reached.
