[PATCH RFC 2/2] PCI: Remove MWI and INTX related members from struct pci_devres

[Heiner Kallweit <hkallweit1@gmail.com>]

After patch 1 of the series the original value of register PCI_COMMAND
is restored in pcim_release. Therefore the code removed here isn't
needed any longer.

In a follow-up step pcim_set_mwi() could be removed.
