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: add watchdogs to protect each queue type

Ring the doorbell again for the following scenarios:
* No receives posted but Rx queue not empty after deadline
* No transmits posted but Tx work still pending after deadline
* Admin queue work still pending after deadline

This will help the queues recover in the extremely rare case that
a doorbell is missed by the FW.

net/ionic: add optimized non-scattered Rx/Tx

The code is very similar, but the simple case can skip a few branches
in the hot path. This improves PPS when 10KB mbufs are used.

S/G is enabled on the Rx side by offload DEV_RX_OFFLOAD_SCATTER.
S/G is enabled on the Tx side by offload DEV_TX_OFFLOAD_MULTI_SEGS.

S/G is automatically enabled on the Rx side if the provided mbufs are
too small to hold the maximum possible frame.

To enable S/G in testpmd, add these args:
--rx-offloads=0x2000 --tx-offloads=0x8000
