NLM: Fix sign of length of NLM variable length strings
According to The Open Group's NLM specification, NLM callers are variable
length strings. XDR variable length strings use an unsigned 32 bit length.
And internally, negative string lengths are not meaningful for the Linux
NLM implementation.
Clean up: Make nlm_lock.len and nlm_reboot.len unsigned integers. This
makes the sign of NLM string lengths consistent with the sign of xdr_netobj
lengths.
