MIPS: ralink: Fix clearing the illegal access interrupt
Due to a typo the illegal access interrupt is never cleared in by the interupt handler, causing an effective deadlock on the first illegal access. This was broken since the code was introduced in 5433acd81e87 ("MIPS: ralink: add illegal access driver"), but only exposed when the Kconfig symbol was added, thus enabling the code.
