Tamas Koczka 9f30de9e03 Bluetooth: Collect kcov coverage from hci_rx_work 
Annotate hci_rx_work() with kcov_remote_start() and kcov_remote_stop()
calls, so remote KCOV coverage is collected while processing the rx_q
queue which is the main incoming Bluetooth packet queue.

Coverage is associated with the thread which created the packet skb.

The collected extra coverage helps kernel fuzzing efforts in finding
vulnerabilities.

This change only has effect if the kernel is compiled with CONFIG_KCOV,
otherwise kcov_ functions don't do anything.
