Subject: [PATCH v2] coccinelle: device_attr_show: Remove useless expression STR

Commit ff82e84e80fc ("coccinelle: device_attr_show: simplify patch case")
simplifies the patch case, as a result, STR is no longer needed.

This also helps to fix below coccicheck warning:
> warning: rp: metavariable STR not used in the - or context code
