Eric Dumazet 73bde5a329 ptp: annotate data-race around q->head and q->tail 
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.

Fixes: d94ba80ebb ("ptp: Added a brand new class driver for ptp clocks.")
