examples/ipsec-secgw: fix session mempool initialisation

Creation of a session mempool may fail in the case of a single lcore

In case when there is only one lcore and number of configures SA less
then (0.5 * CDEV_MP_CACHE_SZ) then creation of the mempool fails with
EINVAL. This is because the number of requested items is less than
(cache size * CDEV_MP_CACHE_MULTIPLIER).

Hence, the number of elements in mempool is increased in such cases.

Add support for dequeue, dequeue_burst, ...

DLB does not currently support interrupts, but instead uses
umonitor/umwait if supported by the processor. This allows
the software to monitor and wait on writes to a cache-line.

DLB supports normal and sparse cq mode. In normal mode the
hardware will pack 4 QEs into each cache line. In sparse cq
mode, the hardware will only populate one QE per cache line.
