The 'io_uring_cmd' ioengine returns the status code type and status code of
NVMe CQE [27:17] to io_u in case of errors. The first patch fixes the CQE
value being returned as negative since it's not an errno. The next one is a
trivial patch to support hexadecimal format to 'ignore_error' option to mask
values such as the status type and status code in a more comfortable way.
