Ajay Kaher 7f5eda0e31 ptp: Add error handling for adjfine callback in ptp_clock_adjtime ...

[ Upstream commit 98337d7c87 ]

ptp_clock_adjtime sets ptp->dialed_frequency even when adjfine
callback returns an error. This causes subsequent reads to return
an incorrect value.

Fix this by adding error check before ptp->dialed_frequency is set.
