LU-12477 llite: use generic_error_remove_page()

lustre's internal ll_invalidate_page() is behaviourally identical to
generic_error_remove_page().
In the case of lustre it isn't a memory hardware error that requires
the page being invalidated, it is the loss of a lock, which will likely
result in the data changing on the server.
In either case, we don't want the page to be accessed any more, so the
same removal is appropriate.
