Subject: NFC: st21nfcb: Remove inappropriate kfree on a devm_kzalloc pointer

From: Firo Yang <firogm@gmail.com>

commit 38bd83f04c5e9695011dc5c294e0c4e6a9f9052d upstream.

Since ndev->driver_data is allocated by devm_kzalloc(), we do not
need the inappropriate kfree to free it in driver's remove function.
Freeing will trigger when driver unloads.
