RDMA/cma: Delete useless kfree code

Browse source 
The parameter of kfree function is NULL, so kfree code is useless, delete
it.  Therefore, goto expression is no longer needed, so simplify
it. cma_dev_group is always pre-zero'd before reaching make_cma_ports, so
the NULL set to cma_dev_group->ports is unneeded too.
