[PATCH 3/3] Documentation: kvm: enclose the final closing brace in code block

[Bagas Sanjaya]

Sphinx reported literal block warning:

Documentation/virt/kvm/api.rst:1362: WARNING: Literal block ends without a blank line; unexpected unindent.

The warning is caused by the final closing brace in KVM_SET_USER_MEMORY_REGION
struct definition is not indented as literal code block.

Indent the closing brace to fix the warning.
