ionic: no fw read when PCI reset failed

Browse source

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.
