There is no limit on high "idx" can go. It should be less than
ARRAY_SIZE(data.states) which is 16.
The "data" variable wasn't declared in that scope so I shifted the code
around a bit to make it work. Also I made "idx" unsigned.

This reverts commit 2ba272d7bd.
The issue fixed by this patch is specific to compute rings and the
previous patch was enough. Additionally, this patch as been traced
to strange behavior on some CZ systems so we might as well drop it.
When executing in a PCI passthrough based virtuzliation environemnt, the
hypervisor will usually attempt to send a PCIe bus reset signal to the
ASIC when the VM reboots. In this scenario, the card is not correctly
initialized, but we still consider it to be posted. Therefore, in a
passthrough based environemnt we should always post the card to guarantee
it is in a good state for driver initialization.
However, if we are operating in SR-IOV mode it is up to the GIM driver
to manage the asic state, therefore we should not post the card (and
shouldn't be able to do it either).
v2: add missing semi-colon
