libcli/smb: only copy the parent lease key if SMB2_LEASE_FLAG_PARENT_LEASE_KEY_SET is set

Browse Source 
MS-SMB2 3.3.5.9.11 Handling the SMB2_CREATE_REQUEST_LEASE_V2 Create Context:

  If the SMB2_LEASE_FLAG_PARENT_LEASE_KEY_SET bit is set in the Flags field of
  the request, Lease.ParentLeaseKey MUST be set to the ParentLeaseKey of the
  request.

Found by MS-SMB2-Prototocol-Testsuite test "Compare_Zero_LeaseFlag_ParentLeaseKey".
