sctp_transport_init() is static and never returns NULL. It is only
called by sctp_transport_new(), so change it to void and remove the
redundant return value check.

Changes in v2:
- Remove the 'fail' label and its path as suggested by Xin Long.
- Link to v1: https://lore.kernel.org/all/20251101163656.585550-1-hehuiwen@kylinos.cn
