gve: Move gve_init_clock to after AQ CONFIGURE_DEVICE_RESOURCES call

Browse source 
commit 46e7860ef9 ("gve: Move ptp_schedule_worker to gve_init_clock")
moved the first invocation of the AQ command REPORT_NIC_TIMESTAMP to
gve_probe(). However, gve_init_clock() invoking REPORT_NIC_TIMESTAMP is
not valid until after gve_probe() invokes the AQ command
CONFIGURE_DEVICE_RESOURCES.

Failure to do so results in the following error:

gve 0000:00:07.0: failed to read NIC clock -11

This was missed earlier because the driver under test was loaded at
runtime instead of boot-time. The boot-time driver had already
initialized the device, causing the runtime driver to successfully call
gve_init_clock() incorrectly.
