radv: fix VS prologs with GPL and static binding stride

When a graphics pipeline library is created with only the vertex input
state, the driver binds this state at pipeline bind time. Though the
vertex binding stride is not necessarily dynamic, in this case the
pipeline stride should be used.

This fixes GPU hangs with recent
dEQP-VK.pipeline.fast_linked_library.vertex_input.*.
