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.
