Second part of fix for 6875 - trans2 FIND_FIRST2 response --> FIND_FIRST2 Data -> Fille Attributes are returned as 0x220 for LANMAN2.1 dial

Ensure dos_mode can return FILE_ATTRIBUTE_NORMAL, then filter the returned attributes by protocol level.
This makes us consistant in returning DOS attrs across all replies. Tested on OS/2 by Günter Kukkukk.
Jeremy.
