x86/mm: Use mm_alloc() in poking_init()
commit 3f4c8211d982099be693be9aa7d6fc4607dff290 upstream.
Instead of duplicating init_mm, allocate a fresh mm. The advantage is
that mm_alloc() has much simpler dependencies. Additionally it makes
more conceptual sense, init_mm has no (and must not have) user state
to duplicate.
