MemorySanitizer discovered instances where the instruction op value was
not assigned.:
WARNING: MemorySanitizer: use-of-uninitialized-value
#0 0x5581c00a76b3 in intel_pt_sample_flags tools/perf/util/intel-pt.c:1527:17
Uninitialized value was stored to memory at
#0 0x5581c005ddf8 in intel_pt_walk_insn tools/perf/util/intel-pt-decoder/intel-pt-decoder.c:1256:25
The op value is used to set branch flags for branch instructions
encountered when walking the code, so fix by setting op to
INTEL_PT_OP_OTHER in other cases.
