transaction: Add new function trans_find_by_lchan
Function returns transaction for given lchan.
In case of active call hold procedure it could be two transactions in a list with links to the same lchan:
* transaction for call on hold
* transaction for active call.
In this case function ignores transaction which was put on hold and returns active call transaction.
