    Revert "zfs readdir: if there were no dirents to copy out, return EINVAL same as UFS"
    
    This reverts commit 9a3edc8d5dbcb896179cfa7867f961184e146a09.
    Apparently returning EINVAL is more aggressive than UFS does it, and
    this causes compatibility issues with apps that actually trigger the
    behavior.
