anv: Disable the SMEM fallback for local memory 

The fallback is incompatible with allocations that use CCS on XeHP. On
that platform, compression can't be used in SMEM.

Apps should be okay with this change. They're able to manage local and
system memory heaps directly (see VK_EXT_memory_budget).
