rkdevflash: don't wait for "Loader" mode after sending spl_loader; …

…show the loop counter

- I thought sending the spl_loader blob puts it into "Loader" mode, but...
- ... turns out "Loader" mode is a separate (rockusb, etc) mode.
- So if in Maskrom mode, just send the loader, and _trust_ it can now WriteLba
- still keeps the timeout, for when a loader is not accepted
