xprtrdma: Enhance MR-related trace points
Two changes: - Show the number of SG entries that were mapped. This helps debug DMA-related problems. - Record the MR's resource ID instead of its memory address. This groups each MR with its associated rdma-tool output, and reduces needless exposure of memory addresses.
