net: add missing bh_unlock_sock() calls
Simon Kirby reported lockdep warnings and following messages :
[104661.897577] huh, entered softirq 3 NET_RX ffffffff81613740
preempt_count 00000101, exited with 00000102?
[104661.923653] huh, entered softirq 3 NET_RX ffffffff81613740
preempt_count 00000101, exited with 00000102?
Problem comes from commit 0e734419
(ipv4: Use inet_csk_route_child_sock() in DCCP and TCP.)
If inet_csk_route_child_sock() returns NULL, we should release socket
lock before freeing it.
Another lock imbalance exists if __inet_inherit_port() returns an error
since commit 093d282321da ( tproxy: fix hash locking issue when using
port redirection in __inet_inherit_port()) a backport is also needed for
>= 2.6.37 kernels.
