Intel-SIG: commit dbb60ac7 x86/fpu: Move fpu__write_begin() to regset.

--------------------------------

The only usecase for fpu__write_begin is the set() callback of regset, so
the function is pointlessly global.

Move it to the regset code and rename it to fpu_force_restore() which is
exactly decribing what the function does.
