Oleg Nesterov e7f180dcd8 x86/fpu: Change xstateregs_get()/set() to use ->xsave.i387 rather than ->fxsave
This is a cosmetic change: xstateregs_get() and xstateregs_set()
abuse ->fxsave to access xsave->i387.sw_reserved.

This practice is correct, ->fxsave and xsave->i387 share the same memory,
but IMHO this looks confusing.

And we can make this code more readable if we add a
"struct xsave_struct *" local variable as well.
