[ovs-dev] [PATCH ovn] tests: fix flaky VXLAN check port/datapath key space limits test

OVN requested-tnl-key VXLAN checks affect tunnel_key in
datapath_binding record only on datapath tunnel key assigning.
If a dp tnl key was already assigned and VXLAN-enabled chassis
is added after that, the value would never be changed.
The test didn't check the VXLAN-enabled chassis was created and
thus test could fail like this:
$ ovn.at:3777: waiting until test x`ovn-nbctl lsp-get-up lsp-bad` = xup...
$ ovn.at:3777: wait succeeded immediately
$ ./ovn.at:3777: ovn-sbctl get Datapath_Binding ls-bad tunnel_key

This patch fixes such fail by adding await for chassis to be
registered in SB DB.
