[PATCH v1 06/15] net/ixgbe/base: fix unchecked return value

[Anatoly Burakov <anatoly.burakov@intel.com>]

From: Barbara Skobiej <barbara.skobiej@intel.com>

There was unchecked return value in the ixgbe_stop_mac_link_on_d3_82599
function. Added checking of return value from the called function
ixgbe_read_eeprom.
