KVM: set_memory_region: Drop user_alloc from prepare/commit_memory_region()
X86 does not use this any more. The remaining user, s390's !user_alloc
check, can be simply removed since KVM_SET_MEMORY_REGION ioctl is no
longer supported.
Note: fixed powerpc's indentations with spaces to suppress checkpatch
errors.
