Add mising braces after an if condition that contains scoped_guard().

This style is both preferred and necessary here, to fix warning after
scoped_guard() change in commit fcc22ac5baf0 ("cleanup: Adjust
scoped_guard() macros to avoid potential warning") to have if-else inside
of the macro. Current (no braces) use in af8133j_set_scale() yields
the following warnings:
af8133j.c:315:12: warning: suggest explicit braces to avoid ambiguous 'else' [-Wdangling-else]
af8133j.c:316:3: warning: add explicit braces to avoid dangling else [-Wdangling-else]

Fixes: fcc22ac5baf0 ("cleanup: Adjust scoped_guard() macros to avoid potential warning")
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202409270848.tTpyEAR7-lkp@intel.com/

I have forgot to add this patch prior to the cited Fixes: commit,
so Stephen Rothwell had to reinvent it, in order to fix linux-next.

I thought I replied to say don't do it this way. Ah well probably went astray
as I was having some email issues yesterday.

Also, for the fixes tag to make sense this will need got through the same tree as
that rather than IIO which doesn't have that commit yet.

Given timing I'm fine with this version getting picked up and if I care enough
I can chase it with a tidy up to the guard() form next cycle.

Thanks, I'll stick it in the locking tree then.
