netfilter: connlabels: change nf_connlabels_get bit arg to 'highest used'
nf_connlabel_set() takes the bit number that we would like to set.
nf_connlabels_get() however took the number of bits that we want to
support.
So e.g. nf_connlabels_get(32) support bits 0 to 31, but not 32.
This changes nf_connlabels_get() to take the highest bit that we want
to set.
Callers then don't have to cope with a potential integer wrap
when using nf_connlabels_get(bit + 1) anymore.
Current callers are fine, this change is only to make folloup
nft ct label set support simpler.
