[PATCH] perf/x86/ibs: Set data_src.mem_lvl_num as well

[Namhyung Kim <namhyung@kernel.org>]

The IBS PMU driver sets data source of memory operations but it missed
mem_lvl_num field.  So I'm adding them here.

Most cases are straight-forward but please check if MEM_LVLNUM_ANY_CACHE
for peer cache hits is ok.  Also I wonder we can add MEM_REMOTE_REMOTE
for peer cache hits in a far CCX.
