/*
* Internal Function: Which sets up ldt chunk array element.
*
* Parameters:
* lchunk - ldt_chunk to be setup
* h_urec - initialized
* keyd - digest of the subrecord
*
* Return value : nothing
*
* Description:
* 1. Sets up transaction and digest
* 2. Sets up the partition reservation (same as parent)
*
* Callers:
* ldt_aerospike_crec_open
* ldt_aerospike_crec_create
