x86/fpu: Call fpu__init_cpu_ctx_switch() from fpu__init_cpu()
fpu__init_cpu() is currently called from fpu__init_system(),
which is the wrong place for it: call it from the proper high level
per CPU init function, fpu__init_cpu().
Note, we still keep the old call site as well, because it depends
on having proper CR0::TS setup. We'll fix this in the next patch.
