Vincent Donnefort d059d8bf2c tracing/remotes: Catch nr_page_va overflow in ring_buffer_desc sizing
The number of pages per remote ring buffer is capped by
ring_buffer_desc::nr_page_va (32 bits). A buffer_size large enough to
overflow that field would silently allocate a descriptor smaller than
what was asked for.

Return SIZE_MAX from trace_buffer_desc_size() on nr_page_va overflow.
