perf/core: Fix possible Spectre-v1 indexing for ->aux_pages[]
commit 4411ec1d1993e8dbff2898390e3fed280d88e446 upstream.
> kernel/events/ring_buffer.c:871 perf_mmap_to_page() warn: potential spectre issue 'rb->aux_pages'
Userspace controls @pgoff through the fault address. Sanitize the
array index before doing the array dereference.
