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>
