xprtrdma: Trace unmap_sync calls
->buf_free is called nearly once per RPC. Only rarely does xprt_rdma_free() have to do anything, thus tracing every one of these calls seems unnecessary. Instead, just throw a trace event when that one occasional RPC still has MRs that need to be released. xprt_rdma_free() is further micro-optimized to reduce the amount of work done in the common case.
