net: bridge: fix uninitialized variables when BRIDGE_CFM is disabled
Function br_get_link_af_size_filtered() calls br_cfm_{,peer}_mep_count() that return a count. When BRIDGE_CFM is not enabled these functions simply return -EOPNOTSUPP but do not modify count parameter and calling function then works with uninitialized variables. Modify these inline functions to return zero in count parameter. Fixes: b6d0425b816e ("bridge: cfm: Netlink Notifications.")
