[PATCH] powerpc/pseries: bugfix: balance calls to pci_device_put

Browse source 
Repeated calls to eeh_remove_device() can result in multiple
(and thus unbalanced) calls to pci_dev_put(). Make sure the
pci_device_put() is called only once (since there was only
one call to the matching pci_device_get()).
