[PATCH] KVM: X86: Fix compile error in svm/sev.c

The compiler reported the following compilation errors:

arch/x86/kvm/svm/sev.c: In function ‘sev_pin_memory’:
arch/x86/kvm/svm/sev.c:361:3: error: implicit declaration of function
‘release_pages’ [-Werror=implicit-function-declaration]
release_pages(pages, npinned);
^~~~~~~~~~~~~

The reason is that the 'pagemap.h' header file is not included.
