net: airoha: Fix typo in REG_CDM2_FWD_CFG configuration

Fix typo in airoha_fe_init routine configuring CDM2_OAM_QSEL_MASK field
of REG_CDM2_FWD_CFG register.
This bug is not introducing any user visible problem since Frame Engine
CDM2 port is used just by the second QDMA block and we currently enable
just QDMA1 block connected to the MT7530 dsa switch via CDM1 port.

Introduced by commit 23020f049327 ("net: airoha: Introduce ethernet
support for EN7581 SoC")
