[dpdk-dev] [PATCH] net/ixgbe: correct error when SFP not present

[Wei Dai <wei.dai@intel.com>]

Ignore the error=IXGBE_ERR_SFP_NOT_PRESENT when SFP is not present.
If it is not ignored, testpmd will in the NIC initialization process.
Ixgbe kernel driver ignores this error and works well. So DPDK
does same thing.
