fiq_fsm: Push error recovery into the FIQ when fiq_fsm is used
If the transfer associated with a QTD failed due to a bus error, the HCD
would retry the transfer up to 3 times (implementing the USB2.0
three-strikes retry in software).
Due to the masking mechanism used by fiq_fsm, it is only possible to pass
a single interrupt through to the HCD per-transfer.
In this instance host channels would fall off the radar because the error
reset would function, but the subsequent channel halt would be lost.
Push the error count reset into the FIQ handler.
