Ian Rogers 97b6b4ac1c perf metrics: Fix segv for metrics with no events 
A metric may have no events, for example, the transaction metrics on
x86 are dependent on there being TSX events. Fix a segv where an evsel
of NULL is dereferenced for a metric leader value.

Fixes: a59fb796a36b ("perf metrics: Compute unmerged uncore metrics individually")
