HID: cp2112: fix sleep-while-atomic
A recent commit fixing DMA-buffers on stack added a shared transfer
buffer protected by a spinlock. This is broken as the USB HID request
callbacks can sleep. Fix this up by replacing the spinlock with a mutex.
Fixes: 1ffb3c40ffb5 ("HID: cp2112: make transfer buffers DMA capable")
