net/ionic: group descriptors when using Q-in-CMB

They can be batched together with memcpy, reducing the number
of PCIe transactions. This improves transmit PPS by up to 50% in
some configurations.

net/ionic: use standard boolean type

Any DPDK public header file which includes stdbool.h may conflict with
local definition of bool, if any, which further results in compilation
error. To avoid, used standard stdbool.h instead of defining bool
internally.

I observed this issue during a development where I included rte_uuid.h
into rte_ethdev.h. As rte_ethdev.h is included to PMD driver, it started
throwing error as given below:
