Added `spdk_nvme_ns_cmd_write_uncorrectable`.



Added new error handling and reporting functionality. This includes several

new API functions to facilitate applications recovering when a qpair or

controller fails.



`spdk_nvme_ctrlr_reconnect_io_qpair` - Reconnects a failed I/O qpair.

`spdk_nvme_ctrlr_set_trid` - Sets the trid of an existing controller. Can be used to

change the trid for failover cases.

`spdk_nvme_ctrlr_is_failed` - Returns the failed state of a controller.

`spdk_nvme_ctrlr_fail` - Forces a controller into a failed state.



Modified the return behavior of several API functions to better indicate to

applications when a qpair is failed. This list of functions includes:



`spdk_nvme_qpair_process_completions`

`spdk_nvme_ns_cmd_*`

`spdk_nvme_ctrlr_process_admin_completions`

`spdk_nvme_ctrlr_cmd_*`



These functions now return -ENXIO when the qpair or controller on which they

operate is failed.
