serial: doc: Use port->state instead of info
As of commit ebd2c8f6d2ec4012 ("serial: kill off uart_info"), the circular transmission buffer is part of struct uart_state instead of struct uart_info. Make it clear this structure is pointed to from struct uart_port. Change 'circ' to 'circ_buf' to match the structure name while we're at it.
