Subject: [PATCH] kcapi-hasher: Fix command-line parsing

I made a mistake in commit 3be3e18d4a2e ("kcapi-hasher: Allow picking
basename via cmdline"), which apparently broke command-line parsing when
the '-n' options is not used. This patch fixes the issue by resetting
the right variable and also silences error messages when checking for
the '-n' option.
