xhci has a fixed number of 24 (TD_QUEUE) XHCITransfer structs per endpoint, which turns out to be a problem for usb3 devices with 32 (or more) bulk streams. xhci re-checks the trb rings on every finished transfer to make sure it'll pick up any pending work. But that scheme breaks in case the first transfer of a ring can't be started because we ran out of XHCITransfer structs already. So remove static XHCITransfer array from XHCIEPContext. Use a linked list instead, and allocate/free XHCITransfer as needed. Add helper functions to allocate & initialize and to cleanup & release XHCITransfer structs. That also simplifies trb management, we never have to realloc XHCITransfer->trbs because we don't reuse XHCITransfer structs any more. New dynamic limit for in-flight xhci transfers per endpoint is number-of-streams + 16.
