ionic: no fw read when PCI reset failed
If there was a failed attempt to reset the PCI connection, don't later try to read from PCI as the space is unmapped and will cause a paging request crash. When clearing the PCI setup we can clear the dev_info register pointer, and check it before using it in the fw_running test.
