x86/fpu: Standardize the parameter type of copy_kernel_to_fpregs()
Bring the __copy_fpstate_to_fpregs() and copy_fpstate_to_fpregs() functions
in line with the parameter passing convention of other kernel-to-FPU-registers
copying functions: pass around an in-memory FPU register state pointer,
instead of struct fpu *.
NOTE: This patch also changes the assembly constraint of the FXSAVE-leak
workaround from 'fpu->fpregs_active' to 'fpstate' - but that is fine,
as we only need a valid memory address there for the FILDL instruction.
