[PATCH v3 6/7] adsldp: empty ExecuteSearch() is S_OK, GetFirstRow()/GetNextRow() then return S_ADS_NOMORE_ROWS

[Damjan Jovanovic]

Some search errors are returned from ExecuteSearch(), but empty
search results definitely result in S_OK from ExecuteSearch()
and S_ADS_NOMORE_ROWS from subsequent GetFirstRow()/GetNextRow().

Try 2 adds a test, and doesn't report all errors through
GetFirstRow()/GetNextRow().
