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 Signed-off-by: liuyacan <liuyacan@corp.netease.com> Change-Id: I2b2bf2b272c5b3ca7e4a56af179af12bbcde149d
