KVM: arm64: Reject hyp trace descriptors with fewer than 3 pages
A trace descriptor with 0 nr_page_va allocates a 0-size bpages
backing region, which makes the ring buffer appear unloaded. Reject
descriptors with nr_page_va < 3 in hyp_trace_desc_is_valid() as this is
in any case the lower-limit for simple_ring_buffer.
