smb3: request handle caching when caching directories 



This client was only requesting READ caching, not READ and HANDLE caching

delay closing a handle (e.g. for caching directory contents) we should
be requesting HANDLE as well as READ (as we already do for deferred
close of files).   See MS-SMB2 3.3.1.4 e.g.
