LU-5224 lnet: build failed with MLNX_OFED-2.2

Build lustre client can fail on the SLES11 SP3 with
MLNX_OFED-2.2 against the kernel-3.0.76-0.11, which will
cause the "'pm_qos_req' has incomplete type" error.This patch
put "#include <linux/compat-2.6.h>" in front of
"#include <net/sock.h>" to solve this problem.

This error come with the configure option
"--with-o2ib=/usr/src/ofa_kernel/default/", it affect the
search path of the compiler, which will search the header
files in this directory before the kernel header files
directory.

This patch change this way because "net/sock.h"(exactly is
"linux/netdevice.h") include header file "linux/pm_qos_params.h",
the pm_qos_params.h is exist both in ofa_kernel include
directory and kernel include directory, so we need to put the
linux/compat-2.6.h in front of net/sock.h to solve the
compatible problem.
