migration/multifd: Remove total pages tracing

The total_normal_pages and total_zero_pages elements are used only for
the end tracepoints of the multifd threads. These are not super useful
since they record per-channel numbers and are just the sum of all the
pages that are transmitted per-packet, for which we already have
tracepoints. Remove the totals from the tracing.
