[net-next v2 2/8] igc: Add Receive Descriptor Minimum Threshold Count to clear HW counters

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

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

The statistics of this register are being tracked, however, the register
was inadvertently missed when implementing igc_clear_hw_cntrs_base().
The register is clear on read, so add it to the function so that the
register is cleared when requested so the tracked count is accurate.
