Alexandra Winter 0124fb0ebf s390/iucv: Fix vargs handling in iucv_alloc_device() 
iucv_alloc_device() gets a format string and a varying number of
arguments. This is incorrectly forwarded by calling dev_set_name() with
the format string and a va_list, while dev_set_name() expects also a
varying number of arguments.

Symptoms:
Corrupted iucv device names, which can result in log messages like:
sysfs: cannot create duplicate filename '/devices/iucv/hvc_iucv1827699952'

Fixes: 4452e8ef8c ("s390/iucv: Provide iucv_alloc_device() / iucv_release_device()")
