Subject: [PATCH net-next V7 2/2] ptp: ptp_read should not release queue

Firstly, queue is not the memory allocated in ptp_read;
Secondly, other processes may block at ptp_read and wait for conditions to be
met to perform read operations.

Fixes: 8f5de6fb2453 ("ptp: support multiple timestamp event readers")
