[RFC PATCH 003/162] drm/i915/selftest: handle local-memory in perf_memcpy

[Matthew Auld]

We currently only support WC when mapping device local-memory, which is
returned as a generic -ENOMEM when mapping the object with an
unsupported type. Try to handle that case also, although it's starting
to get pretty ugly in there.
