Subject: [PATCH] parse-events: Handle opcode parsing error

If an invalid opcode is encountered in parsing event print format, the
trace-cmd calls exit() without parsing any other events.

This patch adds handling for such an error where the get_op_prio() is
called. If the return value is -1, then the event print format parsing
is skipped and parsing continues.
