perf: correct SNOOPX field offset

perf_event.h has macros that define the field offsets in thedata_src bitmask in perf records. The SNOOPX and REMOTE offsetswere both 37. These are distinct fields, and the bitfield layoutin perf_mem_data_src confirms that SNOOPX should be at offset 38.Fixes:52839e6 ("perf tools: Add support for printing new mem_info encodings")Signed-off-by: Al Grant <al.grant@foss.arm.com>Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org>Reviewed-by: Andi Kleen <ak@linux.intel.com>Link:https://lkml.kernel.org/r/4ac9f5cc-4388-b34a-9999-418a4099415d@foss.arm.com
