USB: ftdi_sio: re-implement read processing
- Re-structure read processing. - Kill obsolete work queue and always push to tty in completion handler. - Use tty_insert_flip_string instead of per character push when possible. - Fix stalled-read regression in 2.6.31 by using urb status to determine when port is closed rather than port count. - Fix race with open/close by checking ASYNCB_INITIALIZED in unthrottle. - Kill private rx_flag and lock and use throttle flags in usb_serial_port instead.
