This patch fixes in simpler way the bug described in [1] and [2]. It looks like DWC2 is the only UDC driver that doesn't force usb requests to complete in ep_disable() function. This causes described problem, because we have no guarantee that all requests will be completed before unbind of usb function. To fix this problem we force all requests of disabled endpoint to complete. Also currently running request is not handled. This allowed to simplify code of kill_all_requests() function, because 'force' parameter is always set to true, so we don't need it anymore. In s3c_hsotg_rx_data() we change function used to print message when active request is NULL from dev_warn() to dev_dbg(), because such situation is harmless for driver and now it can take place during normal endpoint disabling.
