Currently zcore_reipl_write() always use DIAG308_LOAD_CLEAR to ipl the
system (used by ngdump and zfcpdump to ipl the original kernel after
dumping).
Instead of 'always clear' check OS_INFO_FLAG_REIPL_CLEAR flag and use
either LOAD_CLEAR or LOAD_NORMAL diag308 subcode accordingly.
For that read os_info and check for the valid os_info flags entry
in zcore_reipl_init(). Do not return error on failure (e.g. os_info
checksum error) in order to continue dump processing, considering
that os_info could be corrupted on the panicked system.
