[PATCH v3] perf/ring_buffer: Prefer struct_size over open coded arithmetic

This is an effort to get rid of all multiplications from allocation functions in order to prevent integer overflows [1][2]. As the "rb" variable is a pointer to "struct perf_buffer" and this structure ends in a flexible array: struct perf_buffer { [...] void*data_pages[]; };
