[S390] cio: fix memleak in subchannel validation
When scanning for new subchannels we have a code path where we allocate memory for a struct subchannel, set the device name (which is dynamically allocated now) and do a check if the underlying device is blacklisted - if so we free the subchannel structure. Since we have not set up refcounting at this stage, the device name's memory is lost. Fix this by moving the dev_set_name after the blacklist test. Note: With this patch the init_name for the console subchannel becomes virtually obsolete.
