serial: core: fix potential NULL pointer dereference
The commit 761ed4a94582 ("tty: serial_core: convert uart_close to use
tty_port_close") refactored uart_close() to use tty_port_close(). At the same
time it introduced a potential NULL pointer dereference. Rearrange the code to
avoid kernel crash.
