USB: serial: fix missing locking on fifo in write callback
On errors the fifo was reset without any locking. This could race with
write which do kfifo_put and perhaps also chars_in_buffer and write_room.
Every other access to the fifo is protected using the port lock so
better add it to the error path as well.
