x86/asm/entry: Delay loading sp0 slightly on task switch
The change:
75182b1632a8 ("x86/asm/entry: Switch all C consumers of kernel_stack to this_cpu_sp0()")
had the unintended side effect of changing the return value of
current_thread_info() during part of the context switch process.
Change it back.
This has no effect as far as I can tell -- it's just for
consistency.
