perf/x86/intel/uncore: Fix reference count leak in __uncore_imc_init_box()

pci_get_device() will increase the reference count for the returned
pci_dev, so tgl_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 before exiting from __uncore_imc_init_box(). Add
pci_dev_put() for both normal and error path.
