nfc: nci: free destination parameters when closing a connection
When a connection is closed, nci_core_conn_close_rsp_packet() frees
conn_info but not conn_info->dest_params, which is a separate devm
allocation. Each connect/close cycle leaks one dest_params until the
NFC device is removed. Free dest_params along with conn_info.
Fixes: 9b8d1a4cf2aa ("nfc: nci: Add an additional parameter to identify a connection id")
