[Intel-gfx] [PATCH igt] lib/ioctl_wrappers: handle ENODEV from from GEM_SET_CACHING ioctl

[Imre Deak]

The ENODEV return value was introduced to the GEM_SET_CACHING ioctl to
mean that the given platform doesn't support the requested caching level
(currently only due to a HW issues on BXT A steppings). Handle this as
the other cases where we want to skip the related subtests.
