Incorrect warnings due to WARN_IF_DOC_ERROR=NO

In case we have a simple file like:
```
/// \file

/// \brief void fie
///
/// \param a first arg
/// \param b second arg
/// \param c third arg
void fie0(int a, int b, int c){}
```
and set:
```
WARN_IF_DOC_ERROR=NO
```
we get the warnings:
```
..../aa.h:8: warning: The following parameters of fie0(int a, int b, int c) are not documented:
  parameter 'a'
  parameter 'b'
  parameter 'c'
```

This is due to the new setting `WARN_IF_INCOMPLETE_DOC` (since 1.9.2) and this needs `paramsFound` which is set in `checkArgumentName` but was skipped due to `WARN_IF_DOC_ERROR=NO`.
