ptp: Use ratelimite for freerun error message

[ Upstream commit e9a7795e75b78b56997fb0070c18d6e1057b6462 ]

Replace pr_err() with pr_err_ratelimited() in ptp_clock_settime() to
prevent log flooding when the physical clock is free running, which
happens on some of my hosts. This ensures error messages are
rate-limited and improves kernel log readability.
