liquidio: fix insmod failure when multiple NICs are plugged in
When multiple liquidio NICs are plugged in, the first insmod of the PF
driver succeeds. But after an rmmod, a subsequent insmod fails. Reason is
during rmmod, the PF driver resets the Octeon of only one of the NICs; it
neglects to reset the Octeons of the other NICs.
Fix the insmod failure by adding the missing Octeon resets at rmmod. Keep
a per-NIC refcount that indicates the number of active PFs in a given NIC.
When the refcount goes to zero, then reset the Octeon of that NIC.
