KVM: arm64: Fix bpages backing allocation size in hyp_trace
hyp_trace_buffer_alloc_bpages_backing() computes nr_bpages as
(PAGE_ALIGN(size) / PAGE_SIZE) + 1, whereas trace_remote_alloc_buffer()
takes into account the buffer page header.
Align the bpages backing allocation by using
__calc_nr_pages_ring_buffer_desc(). There's no need to validate
nr_bpages again, it has been before with trace_buffer_desc_size().
