pldm-file: client: send NEXT_PART requests with TransferContext set

Currently, we clear out the TransferContext field of NEXT_PART multipart
receive commands, in line with handling for the offset and length fields
(as required by the spec). However, hosts may be relying on the
TransferContext for subsequent requests too, so don't clear that out
for NEXT_PART reqs.
