libcli/smb: only allow SMB2_LEASE_FLAG_PARENT_LEASE_KEY_SET in lease_flag
MS-SMB2 3.3.5.9.11 Handling the SMB2_CREATE_REQUEST_LEASE_V2 Create Context:
The server MUST attempt to locate a Lease by performing a lookup in the
LeaseTable.LeaseList using the LeaseKey ...
If no lease is found, one MUST be allocated with the following values set:
...
* Lease.Breaking is set to FALSE.
...
Ensures we ignore SMB2_LEASE_FLAG_BREAK_IN_PROGRESS. Found by
MS-SMB2-Prototocol-Testsuite "BreakReadLeaseV2TestCaseS0".
