Subject: ARM: KVM: fix kvm_arch_{prepare,commit}_memory_region

Commit f82a8cfe9 (KVM: struct kvm_memory_slot.user_alloc -> bool)
broke the ARM KVM port by changing the prototype of two global
functions.

Apply the same change to fix the compilation breakage.

Subject: ARM: KVM: fix compilation after removal of user_alloc from struct
 kvm_memory_slot

Commit 7a905b1 (KVM: Remove user_alloc from struct kvm_memory_slot)
broke KVM/ARM by removing the user_alloc field from a public structure.

As we only used this field to alert the user that we didn't support
this operation mode, there is no harm in discarding this bit of code
without any remorse.
