[PATCH v2] RDMA/rtrs: server: Fix error handling in get_or_create_srv

[Ma Ke]

After device_initialize() is called, use put_device() to release the
device according to kernel device management rules. While direct
kfree() might work in some cases, using put_device() ensures proper
device lifecycle management.

Found by code review.
