DFU: restart bootloader when USB conf failed 

when starting the DFU bootloader, but USB configuration (e.g.
enumeration) failed, the MCU restarted in the main application.
this occured after a DFU detach and were the USB host missed the
USB reset.
now after MCU reset, the bootloader is started again, since this
is what was requested to begin with.
the bootloader will always restart in the bootloader until USB
enumeration succeeded.
this boot loop can be stopped by unplugging/removing power from
the device.
