[dpdk-stable] [PATCH v2] net/ixgbe: do not return internal code in rte_eth_dev_reset

[Luca Boccassi]

In case of a temporary failure the ixgbe driver can return the internal
error IXGBE_ERR_RESET_FAILED to the application. Instead, return
-EAGAIN as per the public API specification.

Fixes: cddaf87a1ecb ("lib: fix unused values")

Change title to "net/ixgbe: do not return internal code" to avoid check-git-log error.
