Subject: [PATCH v2] nfc: st95hf: remove unnecessary assignment and label

From: wengjianfeng <wengjianfeng@...ong.com>

In function st95hf_in_send_cmd, the variable rc is assigned then goto
error label, which just returns rc, so we use return to replace it.
Since error label only used once in the function, so we remove error label.
