[PATCH 2/2] trace-cmd: Optimize check_file_exists()

[Steven Rostedt <rostedt@xxxxxxxxxxx>]

From: "Steven Rostedt (VMware)" <rostedt@xxxxxxxxxxx>

       if (dir && !S_ISDIR(st.st_mode))
               return false;
       if (!dir && S_ISDIR(st.st_mode))
               return false;
       return true;

Is the same as:

       return !dir == !S_ISDIR(st.st_mode);

Micro-optimize the logic!
