RDMA/mlx5: Fix flow counter query via DEVX
[ Upstream commit 3e358ea8614ddfbc59ca7a3f5dff5dde2b350b2c ]
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: 208d70f562e5 ("IB/mlx5: Support flow counters offset for bulk counters")
