[PATCH rdma-next 6/7] IB/mlx5: Increase flow table reference count in create rule

[Leon Romanovsky <leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

From: Maor Gottlieb <maorg-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

Move the reference count increasing of flow table to be in
create_flow_rule, it will increase the reference count for each rule
creation and not for each flow.
