ksmbd: only v2 leases handle the directory

Browse Source 
[ Upstream commit 77bebd186442a7d703b796784db7495129cc3e70 ]

When smb2 leases is disable, ksmbd can send oplock break notification
and cause wait oplock break ack timeout. It may appear like hang when
accessing a directory. This patch make only v2 leases handle the
directory.
