[PATCH net-next] octeontx2-af: Use LMAC_AF_ERR codes in CGX handlers

[PATCH net-next] octeontx2-af: Use LMAC_AF_ERR codes in CGX handlers

[nshettyj]

From: Hariprasad Kelam <hkelam@marvell.com>

When a netdev that is not mapped to a MAC block (cgx/rpm) requests a
MAC feature, the AF driver currently returns generic errors like -EPERM.

Replace these generic error codes with driver-specific LMAC_AF_ERR_*
error codes to provide better debugging information.
