Subject: [PATCH net v3] nfc: nci: Fix handling of zero-length payload packets in nci_rx_work()

When nci_rx_work() receives a zero-length payload packet, it should not
discard the packet and exit the loop. Instead, it should continue
processing subsequent packets.

Fixes: d24b03535e5e ("nfc: nci: Fix uninit-value in nci_dev_up and nci_ntf_packet")
