powerpc/pci: Fix build with PCI_IOV=y and EEH=n
Despite attempting to fix this in commit fb36e9073693 ("powerpc/pci: Fix
SRIOV not building without EEH enabled"), the build is still broken when
PCI_IOV=y and EEH=n (eg. g5_defconfig with PCI_IOV=y):
arch/powerpc/kernel/pci_dn.c: In function ‘remove_dev_pci_data’:
arch/powerpc/kernel/pci_dn.c:230:18: error: unused variable ‘edev’
Incorporate Ben's idea of using __maybe_unused to avoid so many #ifdefs.
