[ Upstream commit ca5f8d2dd5229ccacdd5cfde1ce4d32b0810e454 ]
Creating of an SMC-R connection with vlan-id fails, because smc_listen_work() determines the vlan_id of the connection, saves it in struct smc_init_info ini, but clears the ini area again if SMC-D is not applicable. This patch just resets the ISM device before investigating SMC-R availability.
