i965: Don't emit bad packets when no VBs are referenced.

It appears that sometimes Mesa (and I suppose a VS could as well) emits
a program which references no vertex data, and thus we end up with
nr_enabled == 0 even though some VBs are enabled.  We'd end up emitting
VB/VE packet headers of 0xffffffff in that case, leading to GPU hangs.

Bug #22945 (wine with an uncompiled VS)
