octeontx2-af: Fix LMAC config in cgx_lmac_rx_tx_enable

[ Upstream commit b4e9b8763e417db31c7088103cc557d55cb7a8f5 ]

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.
