gve: Move ptp_schedule_worker to gve_init_clock

Browse source

Previously, gve had been only initializing ptp aux work when
hardware timestamping was initialized through ndo_hwtsatmp_set. As this
patch series introduces XDP hardware timestamp metadata which will
require the ptp aux work, the work can't be gated on the
kernel_hwtstamp_config being set and must be initialized elsewhere.

For simplicity, ptp_schedule_worker is invoked right after the ptp_clock
is registered with the kernel (which happens during gve_probe or
following reset). The worker is scheduled in GVE_NIC_TS_SYNC_INTERVAL_MS
as the synchronous call to gve_clock_nic_ts_read makes the worker
redundant if scheduled immediately.

If gve cannot read the device clock immediately, it errors out of
gve_init_clock.
