nfc: nci: complete pending data exchange on device close

In the Linux kernel, the following vulnerability has been resolved:

nfc: nci: complete pending data exchange on device close

In nci_close_device(), complete any pending data exchange before

closing. The data exchange callback (e.g.

rawsock_data_exchange_complete) holds a socket reference.

NIPA occasionally hits this leak:
