1c01c53883 RDMA/cxgb4: Register RDMA provider based on LLD state_change events 
The LLD now supports proper UP state change events, so move the RDMA
provider registration to UP path.

This fixes a crash when loading iw_cxgb4 _after_ the NFS/RDMA
transport is up and running.

fd388ce677 RDMA/cxgb4: Detach from the LLD after unregistering RDMA device 
In the RDMA core unregister path, kernel users will be calling down
into the T4 provider to release resources.  So we cannot detach from
the LLD until this process completes.
