The script originally was incorrectly calling `idc.set_member_cmt` which
takes different arguments to calculate the member struct and offset. And
then it passes the results into the `ida_struct` version. However, this is
already done, so we can just go straight to the `ida_struct` version.
Current script make 1 character for each byte in comment line. So it`s cause double length and incorrect chars in international comments from IDA in Ghidra. This small patch fix it.
