signal/mips: Remove FPE_FIXME usage from mips
Ralf Baechle recently merged a change to stop explicitly handling this
case on mips, as the case is impossible. Unfortunately when the code
in force_fcr31_sig to not use siginfo but a simple interger variable gcc
starts warning about an unitialized variable.
So add a return statement so gcc knows the code never attempts to use
the impossible value.
