sysctl: increase log severity on failed write

Increase the log severity in case of writing to a non existent sysctl
parameter as this can either be caused by a misspelling or a kernel mis-
configuration, e.g. in case YAMA does not get loaded due to a incomplete
lsm= override:

    systemd-sysctl[354]: Couldn't write '1' to 'kernel/yama/ptrace_scope', ignoring: No such file or directory
