anv: Don't re-use entry_point pointer from spirv_to_nir

When running with NIR_TEST_CLONE=1, the pointer will not be valid, as
the whole shader is going to be recreated every pass.  Prefer using
is_entrypoint (to query when looping) and nir_shader_get_entrypoint()
instead.

Fixes the Vulkan Piglit tests
