nvvram: no checksum error recording on WRT54G3GV2(-VF)

The CFE of the WRT54G3GV2 expects two firmware images, if one of them
produces a CRC error (which is the case after you installed OpenWrt, as
there is no second image), it writes one of three consecutive bytes to
the flash. (Look for "Image Status : IMG2_BAD" during boot.)

After the third boot with a CRC error, it stops and waits for a new
firmware image. To prevent this 'noset_try_flag' must be set to 1 on boot.

Tested with my own box.
