Xiongfeng Wang 9b51d072da RDMA/hfi: Decrease PCI device reference count in error path ...

pci_get_device() will increase the reference count for the returned
pci_dev, and also decrease the reference count for the input parameter
*from* if it is not NULL.

If we break out the loop in node_affinity_init() with 'dev' not NULL, we
need to call pci_dev_put() to decrease the reference count. Add missing
pci_dev_put() in error path.
