RDMA/mlx5: Fix Q-counters per vport allocation

Previously Q-counters data was being allocated over the PF for all of
the available vports, however that isn't necessary.

Since each VF or SF has a Q-counter allocated for itself.

So we only need to allocate two counters data structures, one for the
device counters, and one for all the other vports to expose the
representors, since they only need to read from it in order to
determine mainly counters numbers and names, so they can all share.

This in turn also solves a bug we previously had where we couldn't
switch the device to switchdev mode when there were more than 128 SF/VFs
configured, since that is the maximum amount of Q-counters available for
a single port
