KVM: arm64: Fix memory leak in hyp_trace_unload()
During trace remote loading, hyp_trace_load() allocates the descriptor
pages but fails to store the allocated size in trace_buffer->desc_size.
As a result, when unloading the trace buffer, hyp_trace_unload() calls
free_pages_exact() with a size of 0 which fails to free the memory.
Fix this by updating the descriptor size in trace_buffer->desc_size.
