[PATCH -next] s390/cert_store: fix error return code in fill_cs_keyring()

[Yang Yingliang <yangyingliang@xxxxxxxxxx>]

The 'rc' will be re-assigned to 0 after calling get_vcssb(), it
needs be set to error code if create_cs_keyring() fails.

Fixes: 8cf57d7217c3 ("s390: add support for user-defined certificates")
