Subject: Revert "igc: fix a log entry using uninitialized netdev"

From: Sasha Neftin <sasha.neftin@intel.com>

commit 8eef5c3cea65f248c99cd9dcb3f84c6509b78162 upstream.

This reverts commit 86167183a17e03ec77198897975e9fdfbd53cb0b.

igc_ptp_init() needs to be called before igc_reset(), otherwise kernel
crash could be observed. Following the corresponding discussion [1] and
[2] revert this commit.
