x86/fpu: Introduce the x86_task_fpu() helper method
The per-task FPU context/save area is allocated right
next to task_struct, currently in a variable-size
array via task_struct::thread.fpu[], but we plan to
fully hide it from the C type scope.
Introduce the x86_task_fpu() accessor that gets to the
FPU context pointer explicitly from the task pointer.
Right now this is a simple (task)->thread.fpu wrapper.
