ksmbd: only v2 leases handle the directory
commit 77bebd186442a7d703b796784db7495129cc3e70 upstream.
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.
