NFC: fdp: fix incorrect free object
The address of fw_vsc_cfg is on stack. Releasing it with devm_kfree() is incorrect, which may result in a system crash or other security impacts. The expected object to free is *fw_vsc_cfg. Signed-off-by: Pan Bian <bianpan2016@163.com> Signed-off-by: David S. Miller <davem@davemloft.net>
