Fix a double-free when an inp transitions to INP_TIMEWAIT state
after having been dropped.

This fixes enforces in_pcbdrop() logic in tcp_input():

"in_pcbdrop() is used by TCP to mark an inpcb as unused and avoid future packet
delivery or event notification when a socket remains open but TCP has closed."
