perf: correct SNOOPX field offset
[ Upstream commit f3d301c1f2f5676465cdf3259737ea19cc82731f ]
perf_event.h has macros that define the field offsets in the
data_src bitmask in perf records. The SNOOPX and REMOTE offsets
were both 37. These are distinct fields, and the bitfield layout
in perf_mem_data_src confirms that SNOOPX should be at offset 38.
