Log Message:
Restructure the abort code for TD based transfers (ctrl, bulk, intr).

In PR kern/22646 some TDs can be on the done queue when the abort start
and, if this is the case, they need to processed after the WDH interrupt.
Instead of waiting for WDH we release TDs that have been touched by the
HC and replace them with new ones.  Once WDH happens the floating TDs
will be returned to the free list.

Also addresses the issue seen in PR kern/55835

Thanks to both Andreas Gustafsson and Edgar Fuß for testing.  Apologies to
