x86/fpu: Change math_error() to use unlazy_fpu(), kill (now) unused save_init_fpu()
math_error() calls save_init_fpu() after conditional_sti(), this means
that the caller can be preempted. If !use_eager_fpu() we can hit the
WARN_ON_ONCE(!__thread_has_fpu(tsk)) and/or save the wrong FPU state.
Change math_error() to use unlazy_fpu() and kill save_init_fpu().
