Subject: RDMA/cma: add missed unregister_pernet_subsys in init failure
Patch-mainline: v5.5-rc2
Git-commit: 44a7b6759000ac51b92715579a7bba9e3f9245c2
References: jsc#SLE-8449
The driver forgets to call unregister_pernet_subsys() in the error path
of cma_init().
Add the missed call to fix it.
Fixes: 4be74b42a6d0 ("IB/cma: Separate port allocation to network namespaces")
