KVM: arm64: Fix hyp_trace_desc allocation size in hyp_trace_load()
The footprint calculated for struct hyp_trace_desc sizes only
trace_buffer_desc and do not take into account the other fields. It
worked so far thanks to the follow-up PAGE_ALIGN().
Fix the descriptor size and while at it, enforce an overflow check after
PAGE_ALIGN().
