riscv/mm: fix two page table check related issues
Two page table check related issues have been fixed here.
1. Open CONFIG_PAGE_TABLE_CHECK in riscv32, we got a compile error[1]:
error: implicit declaration of function 'pud_leaf'
Add pud_leaf() definition to incluce/asm-generic/pgtable-nopmd.h to fix
this issue.
2. Keep consistent with other pud_xxx() helpers, move pud_user() to
pgtable-64.h and add pud_user() to pgtable-nopmd.h.
