Description

While investigating another problem we noticed that when more than one durable handle shares a lease, only one of them (the lease owner) can be reclaimed.

The error here is from something missed when leases were added.
In the function smb_dh_should_save, we need to look at the state of
the lease when a durable handle has a lease. When a DH has a lease,
the oplock "grant" is stored in the lease (ls_state) and when the DH
is an ordinary oplock, the "grant" is in f_oplock.og_state (simple fix).
