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.
