Apparently Skylake uses init-optimization when saving FPU state, and ptrace() returns XSTATE_BV[0] = 0 meaning FPU was not used by a task (in init state). Since CRIU restore uses sigreturn to restore registers, FPU state is always restored. Fill the state with default values on dump to make restore happy.
