USB: whci-hcd: make endpoint_reset method async
usb_hcd_endpoint_reset() may be called in atomic context and must not
sleep. So make whci-hcd's endpoint_reset() asynchronous. URBs
submitted while the reset is in progress will be queued (on the std
list) and transfers will resume once the reset is complete.
