Add a mutex around the PTM transaction to prevent multiple transactors
Multiple processes try to initiate a PTM transaction, one or all may
fail. This can be reproduced by running two instances of the
following:
$ sudo phc2sys -O 0 -i tsn0 -m
PHC2SYS exits with:
"ioctl PTP_OFFSET_PRECISE: Connection timed out" when the PTM transaction
fails
Note: Normally two instance of PHC2SYS will not run, but one process
should not break another.
