watchdog: iTCO_wdt.c: remove extra pci_dev_put()'s from init code
The iTCO_wdt driver erroneously releases the pci_dev, and causes PCI hotremove
to fail because of an incorrect usage count.
The probe for this driver does a for_each_pci_dev() which gets a reference for
a pci_dev when iTCO_wdt_init() is successful. The for_each_pci_dev() loop
puts a reference for a pci_dev when iTCO_wdt_init() fails, so the
iTCO_wdt_init() does not need to do any pci_dev_put()'s.
The only pci_dev_put() that is required is in the iTCO_wdt_cleanup() function.
