    cp: Revert "If copy_file_range(2) fails with EXDEV, use fall-back."
    
    This reverts commit 64333654908153cd8e2dcb408c57cc3e3c4f29af.
    
    The error is not valid per api contract, it showed up as a regression
    after 15f0b8c309dea1dcb14d3e374686576ff68ac43f
    
    15f0b8c309dea1dc ("zfs: merge openzfs/zfs@9cd71c860 (master)") and was
    subsequently in d012836fb6165494 ("zfs: fix up EXDEV handling for
    clone_range").
