struct pci_dev::driver holds (apart from a constant offset) the same
data as struct pci_dev::dev->driver. With the goal to remove struct
pci_dev::driver to get rid of data duplication replace getting the
driver name by dev_driver_string() which implicitly makes use of struct
pci_dev::dev->driver.

For mlxsw:

Tested-by: Ido Schimmel <idosch@nvidia.com>

Tested with the kexec flow that I mentioned last time. Works fine now.

Thanks
