Commit 2c8a81dc0cc5 ("riscv/mm: fix two page table check related
issues") added pud_user() in include/asm-generic/pgtable-nopmd.h

But pud_user() only exists on ARM64 and RISCV and is not expected
by any part of MM.

Add the missing definition in arch/riscv/include/asm/pgtable-32.h
and remove it from asm-generic/pgtable-nopmd.h

I assume you double checked the riscv cross-builds on both 32/64. It looks
correct:
