perf annotate browser: The idx_asm field should be used in asm only view

When hide_src_view is true we can't use browser_disasm_line->idx, that
takes into account also non asm lines, we must use browser_disasm_line->idx_asm
instead, otherwise we may end up with an index after the number of
entries, oops, fix it.
