[horde] trap invalid opcode/segfault in horde_lz4

[Patrick Domack]

I just updated horde_lz4 yesterday, and am having endless log entries  
about this. I didn't have any of these before I updated, and was  
running the release from when v5.2.0 horde was released.

As to be expected, disabling horde_lz4, cleaned out the crashes.
