RDMA/mlx5: Expose RoCE acceleration counters on all functions

Browse Source 
Decouple RoCE acceleration counters exposure from the roce_accl device
cap. The device cap is intended to protect the access to the roce_accl
register and was disabled on VFs for that purpose.
Reading the acceleration counters, however, does not involve that
register, the counters are read-only statistics that carry no
configuration risk. Gating their exposure on the capability therefore
needlessly hides useful diagnostic data on VFs.
Expose the counters on all functions regardless of the capability.
