MIPS: tlbex: Remove some RIXI redundancy
The cpu_has_rixi cases in build_update_entries are now identical to the
non-RIXI cases with the one exception of the r45k_bvahwbug case which is
hardcoded as never happening anyway & presumably was either missed from
the RIXI path or would never happen on a CPU with RIXI support. Remove
the redundant checks & duplication.
