svcrdma: Remove frmr cache
Clean up: Now that the svc_rdma_recvfrom path uses the rdma_rw API, the details of Read sink buffer registration are dealt with by the kernel's RDMA core. This cache is no longer used, and can be removed. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J. Bruce Fields <bfields@redhat.com>
