SLRT memory region is not memblock_reserved in MLE, yet it was accessed from lateinit. It happened that SLRT was overwritten in the meantime. The fix makes MLE save the copy of LOG_INFO SLRT entry and then make it accessible to lateinit code via slaunch_get_log_info(). Signed-off-by: Szymon "accek" Acedański <accek@invisiblethingslab.com>
