ioctl: convert cmdline_info arrays to named initializers

To get rid of remaining "missing field initializer" compiler warnings,
convert arrays of struct cmdline_info used for command line parser to
named initializers. This also makes the initializers easier to read.

This commit should have no effect on resulting code (checked with gcc-11
and -O2).
