perf pmu: fix alias->snapshot missing initialization bug
This patch fixes a bug in __perf_pmu__new_alias() whereby the alias->snapshot field was not initialized to false. This led to random alias->snapshot value for an alias and was breaking some measurements such as: $ perf stat -a -e uncore_imc/data_reads/ -I 1000 sleep 100 Because the event ended up being treated as snapshot mode, when it is not.
