Subject: [PATCH] nfc: st-nci: Remove unnecessary variable

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

The variable r is defined at the beginning and initialized
to 0 until the function returns r, and the variable r is
not reassigned.Therefore, we do not need to define the
variable r, just return 0 directly at the end of the function.
