signal/mips: Report FPE_FLTUNK for undiagnosed floating point exceptions



Most mips builds fail with

arch/mips/kernel/traps.c: In function ‘force_fcr31_sig’:
arch/mips/kernel/traps.c:732:2: error:
	‘si_code’ may be used uninitialized in this function

Fix the problem by initializing si_code with FPE_FLTUNK (undiagnosed
floating point exception).
