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
