usb: gadget: s3c-hsotg: add flush TX FIFO when kill all requests

Browse source

This patch adds flushing TX FIFO in kill_all_requests() function in
dedicated-fifo mode. It's because when requests are killed (when endpoint is
disabled or in case of device reset/disconnection) in FIFO can stay some
unsent data. In the worst case FIFO can stay full, and then if endpoint will
be back enabled, sending new data will be impossible.
