bridge: cfm: fix enum typo in br_cc_ccm_tx_parse
[ Upstream commit c2b2ee36250d967c21890cb801e24af4b6a9eaa5 ]
It appears that there is a typo in the code where the nlattr array is
being parsed with policy br_cfm_cc_ccm_tx_policy, but the instance is
being accessed via IFLA_BRIDGE_CFM_CC_RDI_INSTANCE, which is associated
with the policy br_cfm_cc_rdi_policy.
This problem was introduced by commit 2be665c3940d ("bridge: cfm: Netlink
SET configuration Interface.").
Though it seems like a harmless typo since these two enum owns the exact
same value (1 here), it is quite misleading hence fix it by using the
correct enum IFLA_BRIDGE_CFM_CC_CCM_TX_INSTANCE here.
