There's a couple reasons not to worry about it, but the primary ones are:
1) The denaturation temperature before RT isn't high enough to melt high MW gDNA
2) Even if gDNA was primed, the template switching mechanism requires the RT to hit a 5' end and neither the RT nor the PCR polymerase are anywhere processive enough to worry about capturing whole chromosomes.
