anv: pipeline cache: fix return value of vkGetPipelineCacheData

According to the spec - 9.6. Pipeline Cache :

  If pDataSize is less than the maximum size that can be retrieved by the
  pipeline cache, at most pDataSize bytes will be written to pData, and
  vkGetPipelineCacheData will return VK_INCOMPLETE.

Fixes the following test from Vulkan CTS :

  dEQP-VK.pipeline.cache.pipeline_from_incomplete_get_data.vertex_stage_fragment_stage
  dEQP-VK.pipeline.cache.pipeline_from_incomplete_get_data.vertex_stage_geometry_stage_fragment_stage
  dEQP-VK.pipeline.cache.misc_tests.invalid_size_test
