Subject: net/smc: keep vlan_id for SMC-R in smc_listen_work()
Git-commit: ca5f8d2dd5229ccacdd5cfde1ce4d32b0810e454
Patch-mainline: 5.4-rc6
References: bnc#1151927 5.3.10
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.
Fixes: bc36d2fc93eb ("net/smc: consolidate function parameters")
