s390/sclp: Fix sclp_init() cleanup on failure

In the Linux kernel, the following vulnerability has been resolved:

s390/sclp: Fix sclp_init() cleanup on failure

If sclp_init() fails it only partially cleans up: if there are multiple
failing calls to sclp_init() sclp_state_change_event will be added several
times to sclp_reg_list, which results in the following warning:

------------[ cut here ]------------

Fix this by removing sclp_state_change_event from sclp_reg_list when
sclp_init() fails.
