mlxsw: pci: Remove mlxsw_pci_sdq_count()
The number of SDQs is stored as part of 'mlxsw_pci' structure. In some
cases, the driver uses this value and in some cases it calls
mlxsw_pci_sdq_count() to get the value. Align the code to use the
stored value. This simplifies the code and makes it clearer that the
value is always the same. Rename 'mlxsw_pci->num_sdq_cqs' to
'mlxsw_pci->num_sdqs' as now it is used not only in CQ context.
