[PATCH] KVM: SVM: Fix build error due to missing release_pages() include

[Borislav Petkov]

From: Borislav Petkov <bp@xxxxxxx>

Fix:

  arch/x86/kvm/svm/sev.c: In function âsev_pin_memoryâ:
  arch/x86/kvm/svm/sev.c:360:3: error: implicit declaration of function ârelease_pagesâ;\
	  did you mean âreclaim_pagesâ? [-Werror=implicit-function-declaration]
    360 |   release_pages(pages, npinned);
        |   ^~~~~~~~~~~~~
        |   reclaim_pages

because svm.c includes pagemap.h but the carved out sev.c needs it too.
Triggered by a randconfig build.

Fixes: eaf78265a4ab ("KVM: SVM: Move SEV code to separate file")
