Edward Adam Davis 1bea2c3e6d ptp: fix corrupted list in ptp_open 
There is no lock protection when writing ptp->tsevqs in ptp_open() and
ptp_release(), which can cause data corruption, use spin lock to avoid this
issue.

Moreover, ptp_release() should not be used to release the queue in ptp_read(),
and it should be deleted altogether.
