xenpaging: remove unused spinlock in pager
The spinlock code in the pager is a no-op because xenpaging is a single
threaded application. There is no locking when put_response() places a
response into the ringbuffer.
The only locking is inside the hypervisor, where mem_event_put_request() and
mem_event_get_response() lock the ringbuffer to protect multiple vcpus from
each other.
