RDMA/mlx5: Fix flow counter query via DEVX

Commit cited in "fixes" tag added bulk support for flow counters but it
didn't account that's also possible to query a counter using a non-base id
if the counter was allocated as bulk.

When a user performs a query, validate the flow counter id given in the
mailbox is inside the valid range taking bulk value into account.

Fixes: 208d70f5 ("IB/mlx5: Support flow counters offset for bulk counters")
