smb3: Add dynamic trace points for RDMA (smbdirect) reconnect
smb3_smbd_connect_done and smb3_smbd_connect_err To improve debugging of RDMA issues add those two. We already had dynamic tracepoints for non-RDMA connect done and error cases. Reviewed-by: Paulo Alcantara (SUSE) <pc@manguebit.com> Signed-off-by: Steve French <stfrench@microsoft.com>
