Mitch Williams 6c1b5bff5a i40e: guard against vf message races
When disabling and enabling VFs on a live system with the VF driver
loaded, it's possible to receive an admin queue message from the VF
driver at an inconvenient time, e.g. when the associated data structures
aren't present or configured. This causes a rather inconvenient panic.

To guard against this, we change the order of when we set num_alloc_vfs
when turning off SR-IOV, and then gate processing of any VF messages
based upon that value. Likewise, when enabling VFs, we shut off the
relevant interrupt until configuration is complete.
