xHCI: set cycle state when allocate rings

In the past all the rings were allocated with cycle state equal to 1.
Now the driver may expand an existing ring, and the new segments shall be
allocated with the same cycle state as the old one.

This affects ring allocation and cached ring re-initialization.
