kernel: mips_disable_fpu: initialize fault_addr in fpu_emulator_cop1Handler

Code calling fpu_emulator_cop1Handler will pass on fault_addr, making gcc
complain about it not being initialized when the FPU emulator is disabled.

Fixes:

arch/mips/kernel/traps.c:864:22: error: 'fault_addr' may be used uninitialized in this function [-Werror=maybe-uninitialized]
