This fixes a compilation error in clang in that a linker section attribute
can't be added to a type.

arch/x86/mm/mmap.c:34:8: error: '__section__' attribute only applies to functions and global variables
struct __read_mostly va_alignment va_align = {
       ^
arch/x86/include/asm/cache.h:10:38: note: expanded from macro '__read_mostly'
#define __read_mostly __attribute__((__section__(".data..read_mostly")))
                                     ^
1 error generated.

By moving the section attribute to the variable declaration, the desired effect
is acheived.
