perf/x86/uncore: Fix potential NULL pointer in uncore_get_alias_name
The current code assumes that the discovery table provides valid
box_ids for the normal units. It's not the case anymore since some units
in the discovery table are broken on some SPR variants.
Factor out uncore_get_box_id(). Check the existence of the type->box_ids
before using it. If it's not available, use pmu_idx.
