USB: ftdi_sio: clean up read completion handler
Remove superfluous error checks in completion handler:
- No need to check private data and urb pointers as we check urb-status
before dereferencing priv (which is not freed until urb has been killed
on close).
- No need to check tty as it is checked again when processing.
- No need to check urb->number_of_packets on bulk urb.
Note that both private data and tty are checked again before processing
(possibly from work queue which also is cancelled on close).
