Implementing a new API get the state if DPDK memory management
APIs are initialized.
One of the use case of this API is while allocating an interrupt
instance, if malloc APIs are ready memory for interrupt handles
should be allocated via rte_malloc_* APIs else glibc malloc APIs
are used. Eg. Alarm subsystem is initialised before DPDK memory
infra setup and it allocates an interrupt handle.
