RDMA/core: Get sum value of all counters when perform a sysfs stat read
Since a QP can only be bound to one counter, then if it is bound to a separate counter, for backward compatibility purpose, the statistic value must be: * stat of default counter + stat of all running allocated counters + stat of all deallocated counters (history stats) Signed-off-by: Mark Zhang <markz@mellanox.com> Reviewed-by: Majd Dibbiny <majd@mellanox.com> Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
