netfilter: nfnetlink_queue: cleanup copy_range usage
For every packet queued, we check if configured copy_range
is 0, and treat that as 'copy entire packet'.
We can move this check to the queue configuration, and can
set copy_range appropriately.
Also, convert repetitive '0xffff - NLA_HDRLEN' to a macro.
[ queue initialization still used 0xffff, although its harmless
since the initial setting is overwritten on queue config ]
