net: dsa: microchip: fix PTP config failure when using multiple ports

When performing the port_hwtstamp_set operation, ptp_schedule_worker()
will be called if hardware timestamoing is enabled on any of the ports.
When using multiple ports for PTP, port_hwtstamp_set is executed for
each port. When called for the first time ptp_schedule_worker() returns
0. On subsequent calls it returns 1, indicating the worker is already
scheduled. Currently the ksz driver treats 1 as an error and fails to
complete the port_hwtstamp_set operation, thus leaving the timestamping
configuration for those ports unchanged.

This patch fixes this by ignoring the ptp_schedule_worker() return
value.
