Subject: ocfs2: fix build failure when TCP/IP is disabled

After commit 12abc5ee7873 ("tcp: add tcp_sock_set_nodelay") and commit
c488aeadcbd0 ("tcp: add tcp_sock_set_user_timeout"), building the kernel
with OCFS2_FS=y but without INET=y causes it to fail with:

ld: fs/ocfs2/cluster/tcp.o: in function `o2net_accept_many':
tcp.c:(.text+0x21b1): undefined reference to `tcp_sock_set_nodelay'
ld: tcp.c:(.text+0x21c1): undefined reference to `tcp_sock_set_user_timeout
'
ld: fs/ocfs2/cluster/tcp.o: in function `o2net_start_connect':
tcp.c:(.text+0x2633): undefined reference to `tcp_sock_set_nodelay'
ld: tcp.c:(.text+0x2643): undefined reference to `tcp_sock_set_user_timeout
'

This is due to tcp_sock_set_nodelay() and tcp_sock_set_user_timeout()
being declared in linux/tcp.h and defined in net/ipv4/tcp.c, which depend
on TCP/IP being enabled.

To fix this, make OCFS2_FS depend on INET=y which already requires NET=y.
