From: Yevgeny Kliteynik <kliteyn@mellanox.com>
Add support for flow steering counters action with
a non-base counter ID (offset) for bulk counters.
When creating a flow counter object, save the bulk value.
This value is used when a flow action with a non-base
counter ID is requested - to validate that the required
offset is in the range of the allocated bulk.

Changelog:
v0 -> v1: https://lore.kernel.org/linux-rdma/20191029055916.7322-1-leon@kernel.org
* Change ffs to multiply bitfmap
* Changed uint32_t to be u32
* Added offset to mlx5_ib_devx_is_flow_counter()

Have you tested this patch without passing offset? because now the
mlx5_ib_devx_is_flow_counter() is done only if MLX5_IB_ATTR_CREATE_FLOW_ARR_COUNTERS_DEVX_OFFSET
is passed.
