Xiongfeng Wang 8ebd16c11c perf/x86/intel/uncore: Fix reference count leak in snr_uncore_mmio_map() 
pci_get_device() will increase the reference count for the returned
pci_dev, so snr_uncore_get_mc_dev() will return a pci_dev with its
reference count increased. We need to call pci_dev_put() to decrease the
reference count. Let's add the missing pci_dev_put().
