perf annotate: Fix a comment about multi_regs in extract_reg_offset function

Browse source 
Fix a comment in function which explains how multi_regs field gets set
for an instruction. In the example, "mov  %rsi, 8(%rbx,%rcx,4)", the
comment mistakenly referred to "dst_multi_regs = 0". Correct it to use
"src_multi_regs = 0"
