ice: Prevent probing virtual functions
The userspace utility "driverctl" can be used to change/override the
system's default driver choices. This is useful in some situations
(buggy driver, old driver missing a device ID, trying a workaround,
etc.) where the user needs to load a different driver.
However, this is also prone to user error, where a driver is mapped
to a device it's not designed to drive. For example, if the ice driver
is mapped to driver iavf devices, the ice driver crashes.
Add a check to return an error if the ice driver is being used to
probe a virtual function.
Fixes: 837f08fdecbe ("ice: Add basic driver framework for Intel(R) E800 Series")
