  Log Message:
  -----------
  ovn-controller: honor ovs_idl_txn when calculating and installing flows.

ovs_idl_txn is checked before various routines (like patch_run) execute.
However, flow calculation and installation does not also check this
variable, which can lead to oscillations as described in [1].
