Pietro Borrello b279fa1cea inet: fix fast path in __inet_hash_connect() 
[ Upstream commit 21cbd90a6f ]

__inet_hash_connect() has a fast path taken if sk_head(&tb->owners) is
equal to the sk parameter.
sk_head() returns the hlist_entry() with respect to the sk_node field.
However entries in the tb->owners list are inserted with respect to the
sk_bind_node field with sk_add_bind_node().
Thus the check would never pass and the fast path never execute.

This fast path has never been executed or tested as this bug seems
to be present since commit 1da177e4c3 ("Linux-2.6.12-rc2"), thus
remove it to reduce code complexity.
