Tom Rix 04c633873c counter: add defaults to switch-statements
Clang static analysis reports this representative problem
counter-chrdev.c:482:3: warning: Undefined or garbage value
  returned to caller
  return ret;
  ^~~~~~~~~~

counter_get_data() has a multilevel switches, some without
defaults, so ret is sometimes not set.
Add returning -EINVAL similar to other defaults.
