Two minor tracing fixes for 6.13:

- Add "const" to "char *" in event structure field that gets assigned
   literals.
 
 - Check size of input passed into the tracing cpumask file.
 
   If a too large of an input gets passed into the cpumask file, it could
   trigger a warning in the bitmask parsing code.
