vulkan: Sanitize pSampleMask in CmdSetSampleMaskEXT

Browse source 
ms.sample_mask is only 16b, while VkSampleMask is 32b and it is allowed
to have all of them set even if maximum 16 samples are supported.

E.g. happens with Zink running supertuxkart:
 supertuxkart: ../../../source/mesa/src/vulkan/runtime/vk_graphics_state.c:2346: vk_common_CmdSetSampleMaskEXT: Assertion `(dyn)->ms.sample_mask == (*pSampleMask)' failed.

  vk_common_CmdSetSampleMaskEXT (commandBuffer=0x5556e903f0, samples=VK_SAMPLE_COUNT_1_BIT, pSampleMask=0x5556819ccc) at vk_graphics_state.c:2346
  zink_draw<(zink_multidraw)1, (zink_dynamic_state)5, true, false> (...) at zink_draw.cpp:639
  zink_draw_vbo<(zink_multidraw)1, (zink_dynamic_state)5, true> (...) at zink_draw.cpp:922
