There are many req leaks when a controller failure
occurs during submitting IO. It must free all of
the children before freeing the parent req.
If a part of the child req has been sent to the back end
and a part of the child req fails, removes the failed req
from the parent req and the parent req must be retained,
freeing the parent req after all of the submitted reqs return.

This change attempts to address the Trello request to decode I/O errors in
NVMe hello_world example.
See https://trello.com/c/MzJJw7hM/2-decode-io-errors-in-nvme-helloworld-example
As part of this change, spdk_nvme_cpl_get_status_string was declared
in nvme.h, and spdk_nvme_qpair_print_command and
spdk_nvme_qpair_print_completion were renamed and added to nvme.h,
allowing all three to used "externally."
To test the failing paths, two compile time defines were added to force a
write or read error (bad LBA) respectively.
As the example does a read after write, if the write fails, the example fails.

When this option is enabled, any failed requests

Of course the application will still receive
