[S390] cio: remove subchannel init_name
We used the init_name to set the console subchannels name early
at the boot stage. With the patch cio: fix memleak in subchannel validation
we moved the name setting to the point where we actually register the
console subchannel. At this time we can do dynamic allocations and therefore
use dev_set_name.
