Added priority elevation to Downstream USB host processing code that
...
interacts with SPI.
It elevates to USB_OTG priority to avoid preemption by SPI, DMA, or USB
interrupts thus avoiding synchronisation issues between USB host stack
and SPI interface.
Also minor improvements to Downstream error handling.
