[PATCH 6.1 195/219] ixgbe: Refactor returning internal error codes

6.1-stable review patch. If anyone has any objections, please let me know.

------------------

From: Jedrzej Jagielski jedrzej.jagielski@intel.com

[ Upstream commit 5795f533f30a80aa0473652876296ebc9129e33a ]

Change returning codes to the kernel ones instead of the internal ones for the entire ixgbe driver.
