MIPS: Fix cpu_has_mips_r2_exec_hazard.

Commit 9cdf30bd3bac697fc533988f44a117434a858f69 upstream.

Returns a non-zero value if the current processor implementation requires
an IHB instruction to deal with an instruction hazard as per MIPS R2
architecture specification, zero otherwise.

For a discussion, see http://patchwork.linux-mips.org/patch/9539/.
