[net PATCH] octeontx2-af: Fix LMAC config in cgx_lmac_rx_tx_enable

From: Hariprasad Kelam

From: Angela Czubak <aczubak@xxxxxxxxxxx>

PF netdev can request AF to enable or disable reception and transmission
on assigned CGX::LMAC. The current code instead of disabling or enabling
'reception and transmission' also disables/enable the LMAC. This patch
fixes this issue.

Fixes: 1435f66a28b4 ("octeontx2-af: CGX Rx/Tx enable/disable mbox handlers")
