Change compute_PDU_Length input parameter to uint32_t.

The total_length parameter in compute_PDU_Length being uint16_t causes
the passed value to be possibly truncated, which can cause the
PDU_Length to be incorrectly calculated.
This change prevents that truncation, since it now matches the size
of the values passed into the function where it is being called.
