Subject: [PATCH] cmdline: avoid garbage in unused fields of parsed result

[ upstream commit 0bf876008f4e51d8c006a3adb3866f0c35c33fbb ]

The result buffer was not initialized before parsing, inducing garbage
in unused fields or padding of the parsed structure.

Initialize the result buffer each time before parsing.

Fixes: af75078fece3 ("first public release")
