BVT_Leasing_FileLeasingV2 occasionally fails

[gwr]

I see this occasionally when running the WPTS, category BVT, SMB2 tests.
This appears to be a test bug in BVT_Leasing_FileLeasingV2.
This test usually passes, and always passes for me if I run that test alone.

When run along with all the BVT SMB2 tests, the test client occasionally
returns an incorrect response to the server's lease break notification,
where the lease break had state going from 3 to 0, and the
lease break acknowledgment had state 3 (should be zero).

Details of those two packets:

That fix works well for me. Thank-you very much.
