x86/fpu: Introduce task_disable_lazy_fpu_restore() helper
x86/fpu: Introduce task_disable_lazy_fpu_restore() helper

Currently there are a few magic assignments sprinkled through the
code that disable lazy FPU state restoring, some more effective than
others, and all equally mystifying.

It would be easier to have a helper to explicitly disable lazy
FPU state restoring for a task.
