Per cxl r3.2 Section 9.13.3.3, extent capacity tracking should include extents in different states including added, pending, etc. Before the change, for the in-device extent number tracking purpose, we only have "total_extent_count" defined, which only tracks the number of extents accepted. However, we need to track number of extents in other states also, for now it is extents pending-to-add. To fix that, we introduce a new counter for dynamic capacity "nr_extents_accepted" which explicitly tracks number of the extents accepted by the hosts, and fix "total_extent_count" to include both accepted and pending extents counting.
