RDMA/cxgb4: Don't re-init wait object in init/fini paths

commit db8b10167126d72829653690f57b9c7ca53c4d54 upstream.

Re-initializing the wait object in rdma_init()/rdma_fini() causes a
timing window which can lead to a deadlock during close.  Once this
deadlock hits, all RDMA activity over the T4 device will be stuck.

There's no need to re-init the wait object, so remove it.
