perf/x86: Fix missing sample size update on AMD BRS

Browse source

It missed to convert a PERF_SAMPLE_BRANCH_STACK user to call the new
perf_sample_save_brstack() helper in order to update the dyn_size.
This affects AMD Zen3 machines with the branch-brs event.

Fixes: eb55b455ef ("perf/core: Add perf_sample_save_brstack() helper")
