Fix ubsan: shift exponent is too large 
When running libzpool with the Undefined Behavior Sanitizer (ubsan)
enabled, a zpool create causes a run-time error:

    module/zfs/vdev_label.c:600:14: runtime error: shift exponent 64 is
    too large for 64-bit type 'long long unsigned int'`

in vdev_config_generate()

Fix is to convert vdev_removal_max_span to its base-2 logarithm, using
highbit64(), and then compare the "shifts".
