mlxsw: pci: Do not setup tasklet from operation
Currently, the structure 'mlxsw_pci_queue_ops' holds a pointer to the
callback function of tasklet. This is used only for EQ and CQ. mlxsw
driver will use NAPI in a following patch set, so CQ will not use tasklet
anymore. As preparation, remove this pointer from the shared operation
structure and setup the tasklet as part of queue initialization.
For now, setup tasklet for EQ and CQ. Later, CQ code will be changed.
