pata_ali: misplaced pci_dev_put() 

The ali_init_one() function does a search for an isa_bridge,
but then fails to release it if the revision information was
not correctly found.

the problem comes from:
	isa_bridge = pci_get_device(...);
	if (isa_bridge && ...) {
		pci_dev_put(isa_bridge);
	}

where the pci_dev_put() is never called if isa_bridge
was valid but the extra checks on the chip-revision
fail to match.
