Yuchung Cheng a6fc8314dc tcp: fix TCP socket rehash stats mis-accounting 
commit 9c30ae8398b0813e237bde387d67a7f74ab2db2d upstream.

The previous commit 32efcc06d2 ("tcp: export count for rehash attempts")
would mis-account rehashing SNMP and socket stats:

  a. During handshake of an active open, only counts the first
     SYN timeout

  b. After handshake of passive and active open, stop updating
     after (roughly) TCP_RETRIES1 recurring RTOs

  c. After the socket aborts, over count timeout_rehash by 1

This patch fixes this by checking the rehash result from sk_rethink_txhash.

Fixes: 32efcc06d2 ("tcp: export count for rehash attempts")
