[PATCH] perf: correct SNOOPX field offset

[Al Grant]

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.

Fixes: 52839e653b5629bd ("perf tools: Add support for printing new 
mem_info encodings")
