x86-64: move unlazy_fpu() into lazy cpu state part of context switch
Make sure that unlazy_fpu()'s stts gets batched along with the other
cpu state changes during context switch. (32-bit already does this.)
This makes sure it gets batched when running paravirtualized.
[ Impact: optimise paravirtual FPU context switch ]
