net/smc: use separate memory regions for RMBs
SMC currently uses the unsafe_global_rkey of the protection domain,
which exposes all memory for remote reads and writes once a connection
is established. This patch introduces separate memory regions with
separate rkeys for every RMB. Now the unsafe_global_rkey of the
protection domain is no longer needed.
