usb: fastboot: fix potential buffer overflow cb_getvar tries to prevent overflowing the response buffer by using strncat. But strncat takes the number of data bytes copied as a limit not the total buffer length so it can still overflow. Pass the correct value instead. cc: Sebastian Andrzej Siewior <bigeasy@linutronix.de> cc: Rob Herring <robh@kernel.org> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>
