Daniel Borkmann e572ff80f0 bpf: Make 32->64 bounds propagation slightly more robust ...

Make the bounds propagation in __reg_assign_32_into_64() slightly more
robust and readable by aligning it similarly as we did back in the
__reg_combine_64_into_32() counterpart. Meaning, only propagate or
pessimize them as a smin/smax pair.
