interconnect: Always call pre_aggregate before aggregate

Browse Source 
commit 73606ba9242f8e32023699b500b7922b4cf2993c upstream.

The pre_aggregate callback isn't called in all cases before calling
aggregate. Add the missing calls so providers can rely on consistent
framework behavior.

Fixes: d3703b3e25 ("interconnect: Aggregate before setting initial bandwidth")
