Log Message:
Apply patch in PR kern/44907 (crash due to race in ehci.c):
- make sure to remove abort_task in ehci_freex
- always initialize abort_task in ehci_allocx,
not in ehci_timeout just before adding the task
Also apply similar fixes to ohci and uhci.
XXX: should we also call abort_task handler before removing it from queue
if *hci_freex() is called for usbd_xfer_handle with queued abort_task?
