[partition] Remove unused parameter

- there are no consumers for checking-the-capacity-of-the-drive

This parameter was introduced in 3cd18fd285 as "preparatory work"
but never completed. The architecture of the PartitionCoreModule
makes it very difficult to get the necessary parameters to
the right place, and it would probably be better to put
a SortFilterProxyModel in front of a partitioning model anyway.

Since the display code can already filter on size, just drop this one.
