timers: Adjust a kernel-doc comment

Those three warnings can easily solved by using :: to indicate a
code block:

	./kernel/time/timer.c:1259: WARNING: Unexpected indentation.
	./kernel/time/timer.c:1261: WARNING: Unexpected indentation.
	./kernel/time/timer.c:1262: WARNING: Block quote ends without a blank line; unexpected unindent.

While here, align the lines at the block.
