MIPS: fpu.h: Fix build when CONFIG_BUG is not set

__enable_fpu produces a build failure when CONFIG_BUG is not set:

In file included from arch/mips/kernel/cpu-probe.c:24:0:
arch/mips/include/asm/fpu.h: In function '__enable_fpu':
arch/mips/include/asm/fpu.h:77:1: error: control reaches end of non-void function [-Werror=return-type]

This is regression introduced in 3.14-rc1. Fix that.
