[Intel-gfx] [PATCH i-g-t] i915/gem_exec_capture: Really confirm error capturing is enabling

[Chris Wilson]

If the device has error capturing disabled, we still allow previous
error state to be cleared by a write to sysfs/error. To actually confirm
that we can capture a fresh error state, we have to perform a read().
