Introduce receive optimisation to dets calls

[ssmyczynski]

Current implementation of dets:req/2 function in dets module is not using receive optimisation.

Module dets is used as a backend for mnesia's disc_only_copies tables. All dirty operations, or symmetric transactions (sym_trans) are executed in context of a single mnesia_tm process which means that in case of using disc_only_copies tables we are actually vulnerable to non-optimised dets calls in case when mnesia_tm message queue is busy.

The proposed solution introduces receive optimisation to avoid that potential problem.
