[PATCH v2 0/2] MR7013: odbc32: Add null pointer checks.

[Owen Rudge (＠orudge)]

"erwin Data Modeler" crashes under Wine when making ODBC connections (to native ODBC drivers on macOS via iODBC) due to passing in `NULL` values in places. These checks allow execution to proceed successfully.

  v2: odbc32: Add null pointer checks to update_result_lengths helpers.
      odbc32: Avoid crashing if str is null in debugstr_sqlstr.
