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.
