perf intel-bts: Fix off-by-one in auxtrace_info minimum size check
Same pattern as the Intel PT fix: min_sz is set to
sizeof(u64) * INTEL_BTS_SNAPSHOT_MODE, but the code accesses
auxtrace_info->priv[INTEL_BTS_SNAPSHOT_MODE], which requires at least
INTEL_BTS_SNAPSHOT_MODE + 1 elements.
Use (INTEL_BTS_SNAPSHOT_MODE + 1) to ensure the highest accessed index
is within bounds.
Fixes: d0170af7004dce9c ("perf tools: Add Intel BTS support")
