From: Nicolai Hähnle <nicolai.haeh...@amd.com>
Together with "radeonsi: fix the R600_RESOURCE_FLAG_UNMAPPABLE check",
this ensures that sparse buffers are placed in VRAM.
Noticed by an assertion that started triggering with commit d4fac1e1d7
("gallium/radeon: enable suballocations for VRAM with no CPU access")
Fixes KHR-GL45.sparse_buffer_tests.BufferStorageTest in debug builds.
