[PATCH] eal/ipc: stop async IPC loop on callback request

[Anatoly Burakov <anatoly.burakov@intel.com>]

EAL did not stop processing further asynchronous requests on
encountering a request that should trigger the callback. This
resulted in erasing valid requests but not triggering them.

Fix this by stopping the loop once we have a request that we
can trigger. Also, remove unnecessary check for trigger
request being NULL.
