RDMA/cxgb4: Call iwpm_init() only once
We need to only register with the iwpm core once. Currently it is
being done for every adapter, which causes a failure for each adapter
but the first, making multiple adapters unusable.
Fixes: 9eccfe109b27 ("RDMA/cxgb4: Add support for iWARP Port Mapper user space service")
