Series PCI: Drop duplicated tracking of a pci_dev's bound driver | expand

Commit Message

A struct pci_driver is supposed to be constant and assigning .err_handler
once per bound device isn't really sensible. Also as the function returns
zero unconditionally let it return no value instead and simplify the
callers accordingly.

As a side effect this removes one user of struct pci_dev::driver. This
member is planned to be removed.
