From: Minfei Huang <mnfhuang@xxxxxxxxx>
Subject: kexec: remove unnecessary test in kimage_alloc_crash_control_pages()
Transforming PFN(Page Frame Number) to struct page is never failure, so we
can simplify the code logic to do the image->control_page assignment
directly in the loop, and remove the unnecessary conditional judgement.
