kernel/sys.c: fix "warning: do-while statement is not a compound statement" noise

do_each_thread/while_each_thread wrap a block of code that is in this format:

	for (...)
		do
			...
		while

If curly braces do not surround the inner loop the following warning is
generated by sparse:

	warning: do-while statement is not a compound statement

Fix the warning by adding the braces.
