dpaa2-switch: fix default return of dpaa2_switch_flower_parse_mirror_key

Browse source

Clang static analysis reports this representative problem
dpaa2-switch-flower.c:616:24: warning: The right operand of '=='
  is a garbage value
  tmp->cfg.vlan_id == vlan) {
                   ^  ~~~~
vlan is set in dpaa2_switch_flower_parse_mirror_key(). However
this function can return success without setting vlan.  So
change the default return to -EOPNOTSUPP.
