kexec: fix build error when hugetlbfs is disabled

free_huge_page() is undefined without CONFIG_HUGETLBFS and there's no
need to filter PageHuge() page is such a configuration either, so avoid
exporting the symbol to fix a build error:

   In file included from kernel/kexec.c:14:0:
   kernel/kexec.c: In function 'crash_save_vmcoreinfo_init':
   kernel/kexec.c:1623:20: error: 'free_huge_page' undeclared (first use in this function)
     VMCOREINFO_SYMBOL(free_huge_page);
                       ^

Introduced by commit 8f1d26d0e59b ("kexec: export free_huge_page to
VMCOREINFO")
