riscv: Use an atomic xchg in pudp_huge_get_and_clear()
commit 546e42c8c6d9498d5eac14bf2aca0383a11b145a upstream.
Make sure we return the right pud value and not a value that could
have been overwritten in between by a different core.
Fixes: c3cc2a4a3a23 ("riscv: Add support for PUD THP")

[pjw@kernel.org: use xchg rather than atomic_long_xchg; avoid atomic op for !CONFIG_SMP like x86]
