USBGadgetHAL: Set Diag DLOAD PID

If QC VID/PID is used and Diag appears as the first function,
write the PID value to the diag driver so it can update the DLOAD
cookie in IMEM.  This will allow for RAMDUMP mode to re-enumerate
using the same VID/PID to avoid any COM port reassignment when
re-enumerating on Windows.
