radv/ac: Fix shared memory offset calculation
The index passed to get_shared_memory_ptr is an attribute slot index,
i.e. the index of a vec4 within LDS. Therefore this must be scaled by
sizeof(vec4) to give the LDS byte offset.
Fixes: f4e499ec791 ("radv: add initial non-conformant radv vulkan driver")
