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
A stub pud_user() is also required for ARM64 after
commit ed928a3402d8 ("arm64/mm: fix page table check compile
error for CONFIG_PGTABLE_LEVELS=2")
