nfc: nci: fix the UAF of rf_conn_info object
commit 1b1499a817c90fd1ce9453a2c98d2a01cca0e775 upstream.
The nci_core_conn_close_rsp_packet() function will release the conn_info
with given conn_id. However, it needs to set the rf_conn_info to NULL to
prevent other routines like nci_rf_intf_activated_ntf_packet() to trigger
the UAF.
