In anv_shader_lower_nir() we call anv_ensure_fp64_shader() only if
device->fp64_nir is set, but the function that sets device->fp64_nir
is anv_ensure_fp64_shader()! That means the only way for
device->fp64_nir to be set is through blorp: if the app does not issue
the blorp shader that uses fp64, then we won't have it.

Change the check to be like the one we have in blorp_compile_fs_brw().
