TTY: serial_core, remove invalid test
tty->index (named here as line) is set up in initialize_tty_struct.
The value is checked in get_tty_driver for the found driver as:
if (device < base || device >= base + p->num)
continue;
*index = device - base;
So index/line can never be more than driver->num. Hence remove this
test from uart_open.
