smb3: request handle caching when caching directories

Browse Source 
commit 9ed9d83a51a9636d367c796252409e7b2f4de4d4 upstream.

This client was only requesting READ caching, not READ and HANDLE caching
in the LeaseState on the open requests we send for directories.  To
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.
