s390/smsgiucv_app: Make use of iucv_alloc_device()
Make use of iucv_alloc_device() to get rid of quite some code. In addition
this also removes a cast to an incompatible function (clang W=1):
drivers/s390/net/smsgiucv_app.c:176:26: error: cast from 'void (*)(const void *)' to 'void (*)(struct device *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict]
176 | smsg_app_dev->release = (void (*)(struct device *)) kfree;
