u_vbuf: don't try to delete NULL driver CSO

Browse source 
Since 18a8c3f7f1 we don't create a driver CSO if there are any
incompatible elements, so only ask backends to delete it if it exists.

Fixes multiple CTS crashes in V3D.

Fixes: 18a8c3f7f1 ("u_vbuf: Only create driver CSO if no incompatible elements")
