mcb: Acquire reference to device in probe

Browse Source 
mcb_probe() does not aqcuire a reference to the probed device but drops one
when removing the device. As it is actually using the device, it should grab
a reference via get_device().

This could lead to a panic found with a rmmod/modprobe stress test
