[net-next v2 7/8] igc: Clean up the hw_stats structure

[Tony Nguyen <anthony.l.nguyen@intel.com>]

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

Remove ictxptc, ictxatc, cbtmpc, cbrdpc, cbrmpc and htcbdpc fields from
the hw_stats structure. Accordance to the i225 device
specification these fields not in use.
This patch come to clean up the driver code.
