CVE: NA

Reference: N/A

----------------------------------------------------------------

since the dereferencing freed memory 'box' in uncore_pci_remove() will
trigger a use-after-free bug, use a variable 'name' to store the value of
box->pmu->type->name, so that the memory 'box' won't be dereferenced after
being released.
