Remove queryCheckstop() function

This function was intended to be used to query if a system checkstop
attention was detected. The query can only check for chip checkstops,
but not all chip checkstops are system checkstops and this project is
agnostic to chip type specifics. So, this query could give invalid
results if a signature was from a chip that would not directly result in
a system checkstop.
