[PATCH 1/2] Revert "igc: fix a log entry using uninitialized netdev"

[Mika Westerberg <mika.westerberg@linux.intel.com>]

This reverts commit 86167183a17e03ec77198897975e9fdfbd53cb0b.

The commit in question moved call to igc_ptp_init() to happen after
igc_reset() which calls igc_ptp_reset() with the spinlock not yet
initialized so we get following splat:

 BUG: spinlock bad magic on CPU#4, udevd/249
  lock: 0xffff98f317e6d4b0, .magic: 00000000, .owner: <none>/-1, .owner_cpu: 0
 CPU: 4 PID: 249 Comm: udevd Not tainted 6.10.0-rc1+ #1312
 Call Trace:

  igc_reset+0xba/0x100 [igc]
  igc_probe+0x7d1/0xa10 [igc]

It is likely that there are other things igc_ptp_init() does that are
required by igc_ptp_reset(), so for this reason revert the commit in
question.
