x86/fpu: Clean up eager_fpu_init() and rename it to fpu__ctx_switch_init()
It's not an xsave specific function anymore, so rename it accordingly
and also clean it up a bit:
- remove the obsolete __init_refok, as the code paths are not
mixed anymore
- rename it from eager_fpu_init() to fpu__ctx_switch_init()
- remove stray 'return;'
- make it static to its only user
