kthread: silence bogus section mismatch warning
WARNING: kernel/built-in.o(.text+0x16910): Section mismatch: reference to .init.text: (between 'kthreadd' and 'init_waitqueue_head') comes because kernel/kthread.c:kthreadd() is not __init but calls kthreadd_setup() which is __init. But this is ok, because kthreadd_setup() is only ever called at init time, and then kthreadd() proceeds into its "for (;;)" loop. We could mark kthreadd __init_refok, but kthreadd_setup() with just one callsite and 4 lines in it (it's been that small since 10ab825bdef8df51) doesn't need to be a separate function at all -- so let's just move those four lines at beginning of kthreadd() itself.
