perf/x86/intel/uncore: Fix refcnt and other cleanups
Fix typo UNCORE_BOX_FLAG_INITIATED to UNCORE_BOX_FLAG_INITIALIZED.
Rename the 'id' parameter in uncore_box_{ref,unref}() to 'die' to
reflect its actual meaning and be consistent with other functions.
box->refcnt is incremented in the PCI PMU register path but has never
been checked or decremented. Although for PCI PMUs box->refcnt
effectively tracks only a single user, add atomic_dec_return() in the
PCI PMU unregister path to make the reference counting complete and
consistent.
