platform-mc: stop multipart PDR processing on TRANSFER_END

PLDM_PLATFORM_TRANSFER_END indicates that the complete PDR
record has been received. After moving the assembled record
into terminus->pdrs, continuing the multipart transfer loop is
unnecessary and can leave a potential post-move access path for
receivedPdr.

Break out of the loop immediately after handling TRANSFER_END
to make the completion condition explicit, simplify control
flow, and resolve the cppcheck accessMoved warning.

No functional change is intended for valid transfers.
