tty: Drop duplicate NULL check in TTY port functions
The free_page(addr), which becomes free_pages(addr, 0) checks addr against 0.
No need to repeat this check in the callers, i.e. tty_port_free_xmit_buf()
and tty_port_destructor().
Note, INIT_KFIFO() is safe without that check, because it operates on
a separate member and doesn't rely on the FIFO itself to be allocated.
