Eric Dumazet c86085585d ptp: annotate data-race around q->head and q->tail ...

[ Upstream commit 73bde5a329 ]

As I was working on a syzbot report, I found that KCSAN would
probably complain that reading q->head or q->tail without
barriers could lead to invalid results.

Add corresponding READ_ONCE() and WRITE_ONCE() to avoid
load-store tearing.
