When a malformed loglevel value (for example "${abc}") is passed on the
kernel cmdline, the loglevel itself is being set to 0.
That then suppresses all following messages, including all the errors
and crashes caused by other malformed cmdline options. This could make
debugging process quite tricky.
This patch leaves the previous value of loglevel if the new value is
incorrect and reports an error code in this case.
