From: Petr Tesarik <ptesarik@xxxxxxxx>
The modules may need to parse the arguments again after
kexec_file_load(2) failed, but getopt is not reset.
This change fixes the --initrd option on s390x. Without this patch,
it will fail to load the initrd on kernels that do not implement
kexec_file_load(2).
