Anton Staaf bb0c3687e6 USB: Add bounds checking to USB-SPI bridge read 
Previously a bogus rx_count value from the USB hardware could have
caused a buffer overflow while copying from the packet ram to the DMA
bounce buffer.  I'm not sure if it is possible to cause the hardware
to generate a bogus rx_count, I doubt it, but this is now nicely
paranoid
