conntrack: fix coupled-options sanity checkings

This patch extends the generic_opt_check() function to add
extra information on the possible option combinations. Under
some specific situations, like the creation and getting of
a conntrack, you may specify the original or the reply tuple
but at least one MUST be present. This handling has been
always tricky, it still remains but we're more user friendly
at least.
