serial: altera_jtaguart: handle uart_add_one_port() failures
altera_jtaguart_probe() maps the register window before registering the
UART port, but it ignores failures from uart_add_one_port(). If port
registration fails, probe still returns success and the mapping remains
live until a later remove path that is not part of probe failure cleanup.
Return the uart_add_one_port() error and unmap the register window on
that failure path.
This issue was identified during our ongoing static-analysis research while
reviewing kernel code.
