session: avoid vpp deadlock due to app crash

In high traffic scenarios, if app crashed or hang on somewhere, app_mq
will quickly accumulate to full, after which vpp worker will try 100
times before giving up allocating slot for every msg. This will cause
vpp main thread barrier sync to fail.

Type: fix
