[PATCH] net: always include tcp.h in sock.c

[Arnd Bergmann <arnd@arndb.de>]

kernelci reports a build regression in the latest 4.12 snapshots
in configurations without TCP:

net/core/sock.c: In function 'skb_orphan_partial':
net/core/sock.c:1810:6: error: implicit declaration of function 'skb_is_tcp_pure_ack' [-Werror=implicit-function-declaration]

The declaration is simply missing because the header is included
conditionally. There is no real reason to leave out the header, so
this just removes the #ifdef.

Fixes: f6ba8d33cfbb ("netem: fix skb_orphan_partial()")
