====================
net/smc: get rid of unsafe_global_rkey

The smc code uses the unsafe_global_rkey, exposing all memory for
remote reads and writes once a connection is established.
Here is now a patch series to get rid of unsafe_global_rkey usage.
Main idea is to switch to SG-logic and separate memory regions for RMBs.
