For multi block dev, the upgrade tool support to switch
block dev, however, if switch to usb3, the current code
will do rkusb_fini() to reinitialize the g_rkusb->ums,
and get the default the block dev.
Test on RK3576 EVB1 with EMMC and UFS block device.
1. Enter Maskrom.
2. Download loader.
3. Switch to EMMC via upgrade tool.
4. Switch to USB3 via upgrade tool.
We can find that after switch to usb3, the block dev
switch back to UFS, rather than the expected EMMC.

With this patch, when do switch to usb3, it avoid to
call the rkusb_fini() and rkusb_init().
