tty: serial: qcom_geni_serial: Use signed variable to get IRQ
The platform_get_irq can return error. Assigning the return value to an unsigned variable and checking it for negative value will always return false. Use an intermediate signed variable to get IRQ information, check for any error and then assign it to 'irq' variable inside uart_port structure.
