    drm/xe/userptr: Unmap userptrs in the mmu notifier
    
    If userptr pages are freed after a call to the xe mmu notifier,
    the device will not be blocked out from theoretically accessing
    these pages unless they are also unmapped from the iommu, and
    this violates some aspects of the iommu-imposed security.
    
    Ensure that userptrs are unmapped in the mmu notifier to
    mitigate this. A naive attempt would try to free the sg table, but
    the sg table itself may be accessed by a concurrent bind
    operation, so settle for only unmapping.
    
    v3:
    - Update lockdep asserts.
    - Fix a typo (Matthew Auld)
