Philipp Rudo a874333de0 s390/kexec_file: fix diag308 subcode when loading crash kernel ...

commit 613775d62e upstream.

diag308 subcode 0 performes a clear reset which inlcudes the reset of
all registers in the system. While this is the preferred behavior when
loading a normal kernel via kexec it prevents the crash kernel to store
the register values in the dump. To prevent this use subcode 1 when
loading a crash kernel instead.
