description:
initalize ci_kfpu_spl, to avoid triggering KASSERT() in fpu_kern_enter()

Follows revision 1.177 of sys/arch/x86/x86/cpu.c:
"""
Add a small API for in-kernel FPU operations.

        fpu_kern_enter();
        /* do FPU stuff */
        fpu_kern_leave();
"""

With this DomU kernel boots with:
[   2.0000571] aes: Intel AES-NI
