Message:

libusbhost: Drop hash_table and use multiple lists instead.

This has several advantages:
Knowing that all endpoints on one address are in one list makes toggle resets more efficient.
Endpoint search is done only once for inserts and deletes.
Lists are part of the structure and not allocated separately, removing one more failure point from init path.
