x86/fpu: Add an __fpregs_load_activate() internal helper
Add a helper function that ensures the floating point registers for the
current task are active. Use with preemption disabled.
While at it, add fpregs_lock/unlock() helpers too, to be used in later
patches.
[ bp: Add a comment about its intended usage. ]
