serial: ma35d1: Validate console index before assignment
The console is immediately assigned to the ma35d1 port without
checking its index. This oversight can lead to out-of-bounds
errors when the index falls outside the valid '0' to
MA35_UART_NR range. Such scenario trigges ran error like the
following:
UBSAN: array-index-out-of-bounds in drivers/tty/serial/ma35d1_serial.c:555:51
index -1 is out of range for type 'uart_ma35d1_port [17]
Check the index before using it and bail out with a warning.
Fixes: 930cbf92db01 ("tty: serial: Add Nuvoton ma35d1 serial driver support")
