MIPS: mm: Fix the cache error vector jump for XKPHYS kernels
except_vec2_generic jumps to cache_parity_error with a j, which cannot
leave the vector's 256MB region. An XKPHYS kernel such as IP30's, linked
at 512MB, is outside it, so the j targets an unbacked address and its
speculative fetch raises bus errors on unrelated fetches. Jump to the
handler's uncached XKPHYS address instead.
Fixes: 7505576d1c1a ("MIPS: add support for SGI Octane (IP30)")
