x86/fpu/xsave: Keep __user annotation in casts 



Don't remove the __user annotation of the fpstate pointer, but
drop the superfluous void * cast instead.

This fixes the following sparse warnings:

  xsave.c:135:15: warning: cast removes address space of expression
  xsave.c:135:15: warning: incorrect type in argument 1 (different address spaces)
  xsave.c:135:15:    expected void const volatile [noderef] <asn:1>*<noident>
  [...]
