Use the order of incoming RAMBlocks from the source to record
an index number; that then allows us to sort the destination
local RAMBlock list to match the source.
Now that the RAMBlocks are known to be in the same order, this
simplifies the RDMA Registration step which previously tried to
match RAMBlocks based on offset (which isn't guaranteed to match).
OK, so, what's the reason for sorting?
If the offset is not gauranteed to match (based on a new patch
that I assume you have coming), then we need to index into
the hashtable based on something that does match, such
as the name you added or some other key.
