iio: magnetometer: fix if () scoped_guard() formatting

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]
