I know we can eliminate the braces, but that does not mean
we should do so: there seems to be no consensus about this
style issue and checkpatch accepts both ways.

Actually, some people prefer to put braces when one of the
if/else-if/else cases has multiple lines. You can see
some examples in kernel/sched/core.c: see hrtick_start(),
sched_fork(), free_sched_domain().

In our case, I thought putting braces would align the else-if
and else and make the code look a bit nicer, but I know this
may be just a matter of personal feeling.

In short, unless the maintainer, Paolo for this file, has any
preference, both ways will be accepted.
