All of initialization success on anv_block_pool_init(), it makes to return VK_SUCCESS. CID 1394319 v2: Fixes from Emil's review: a) Add the return type for propagating the return value to caller. b) Changed anv_block_pool_init() to return VK_ERROR_INITIALIZATION_FAILED on failure of initialization.
