netfilter: nf_tables: add range expression
Inverse ranges != [a,b] are not currently possible because rules are
composites of && operations, and we need to express this:
data < a || data > b
This patch adds a new range expression. Positive ranges can be already
through two cmp expressions:
cmp(sreg, data, >=)
cmp(sreg, data, <=)
This new range expression provides an alternative way to express this.
