net/smc: immediate termination for SMCD link groups
SMCD link group termination is called when peer signals its shutdown of its corresponding link group. For regular shutdowns no connections exist anymore. For abnormal shutdowns connections must be killed and their DMBs must be unregistered immediately. That means the SMCR method to delay the link group freeing several seconds does not fit. This patch adds immediate termination of a link group and its SMCD connections and makes sure all SMCD link group related cleanup steps are finished.
