llrp: limit recursion depth
LLRP defines fairly complex parameter nesting which we handle via recursion,
however this means a large crafted packet could cause very deep stacks and
potentially stack overflows. Limit our recursive depth to an arbitrary, which
should be more than enough for any legitimate packet (I hope).
