net/mlx4_core: pass pci_device_id.driver_data to __mlx4_init_one during reset

The second parameter of __mlx4_init_one() is used to identify whether the
pci_dev is a PF or VF. Currently, when it is invoked in mlx4_pci_slot_reset()
this information is missed.

This patch match the pci_dev with mlx4_pci_table and passes the
pci_device_id.driver_data to __mlx4_init_one() in mlx4_pci_slot_reset().
