[ARM] Add curly braces around switch case [NFC]

My previous commit r304702 introduced a new case into a switch statement.
This case defined a variable but I forgot to add the curly brackets around the
case to limit the scope.

This change puts the curly braces back in so that the next person that adds a
case doesn't get a build failure. Thanks to avieira for the spot.
