[PATCH 7.2 45/82] nfc: nci: free destination parameters when closing a connection

7.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Linmao Li <[email protected]>

commit 2e65bafdfd3a8bba972b3d17b6a57816557530fc upstream.

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")
