When a VF (Virtual Function) driver is removed, the PF (Physical Function)
driver continues to retain stale VF-specific information. This can lead to
inconsistencies or unexpected behavior when the VF is re-initialized or
reassigned.
This patch ensures that the PF driver clears the corresponding VF info
when the VF driver is removed, maintaining a clean state and preventing
potential issues.
