mlxsw: pci: Remove mlxsw_pci_cq_count()
Currently, for each interrupt we call mlxsw_pci_cq_count() to determine the
number of CQs. This call makes additional two function's calls. This can
be removed by storing this value as part of structure 'mlxsw_pci', as we
already do for number of SDQs. Remove the function and
__mlxsw_pci_queue_count() which is now not used and store the value
instead.
