USB: serial/keyspan_pda, fix potential tty NULL dereferences
Make sure that we check the return value of tty_port_tty_get.
Sometimes it may return NULL and we later dereference that.
There are several places to check. For easier handling,
tty_port_tty_get is moved directly to the palce where needed in
keyspan_pda_rx_interrupt.
