net: ravb: Fix possible hang if RIS2_QFF1 happen
Since this driver enables the interrupt by RIC2_QFE1, this driver
should clear the interrupt flag if it happens. Otherwise, the interrupt
causes to hang the system.
Note that this also fix a minor coding style (a comment indentation)
around the fixed code.
