serial-uartlite: fix null pointer dereference on pointer port
Pointer port is dereferenced on port->private_data when assigning pointer
pdata before port is null checked, leading to a potential null pointer
dereference. Fix this by assigning pdata after the null pointer check on
port.
Detected by CoverityScan, CID#1475434 ("Dereference before null check")
Fixes: 3b209d253e7f ("serial-uartlite: Do not use static struct uart_driver out of probe()")
