x86/fpu: Simplify copy_kernel_to_xregs_booting()
copy_kernel_to_xregs_booting() has a second parameter that is the mask of xfeatures that should be copied - but this parameter is always -1. Simplify the call site of this function, this also makes it more similar to the function call signature of other copy_kernel_to*regs() functions.
