CIFS: Fix oplock break handling (try #2)
When we get oplock break notification we should set the appropriate value of OplockLevel field in oplock break acknowledge according to the oplock level held by the client in this time. As we only can have level II oplock or no oplock in the case of oplock break, we should be aware only about clientCanCacheRead field in cifsInodeInfo structure. Also fix bug connected with wrong interpretation of OplockLevel field during oplock break notification processing.
