[PATCH] kexec: cleanup: make add_backup_segments static

[PATCH] kexec: cleanup: make add_backup_segments static

[Zhang Yanfei]

From: Zhang Yanfei <zhangyanfei@cn.fujitsu.com>

The function add_backup_segments is only called by my_load and
they are in the same file. So unnecessary to export it. Make it
static.
