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: d94ba80ebbea ("ptp: Added a brand new class driver for ptp clocks.")
