Do not use counter for error tracking

Current code uses an incrementing counter to check whether a function
returned error:

  errors += some_function();
  if(errors) { goto finish }

Replace with a more standard variable
  errors = some_function();
  if(errors) { goto finish }

Rename 'errors' variable to a more typical 'ret'.

Avoid reporting both ALPM_EVENT_PKG_RETRIEVE_FAILED and
ALPM_EVENT_PKG_RETRIEVE_DONE in the error path.
