[igt-dev] [PATCH i-g-t 2/2] test/i915/gem_eio: Skip suspend test on smallbar machine

[Nirmoy Das]

Suspending machine requires backing up gem objects to
system memory. CPU non-visible lmem objects can only be
backed up with the help of GPU on a smallbar device and if
the gpu is wedged then such backup action will fail with -EIO.

This test sets the gpu to wedge state before suspending the
machine which will always fail on smallbar machine.
