ice: Prevent probing virtual functions

stable inclusion
from stable-5.10.60
commit bae5b521feaa9ce08d7cf0a60c9c955ca76b2cf1
bugzilla: 177018 https://gitee.com/openeuler/kernel/issues/I4EAUG

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=bae5b521feaa9ce08d7cf0a60c9c955ca76b2cf1



--------------------------------

[ Upstream commit 50ac7479 ]

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: 837f08fd ("ice: Add basic driver framework for Intel(R) E800 Series")
