*Description:*
For bug: https://bugs.launchpad.net/linaro-qa/+bug/1327251
Purpose of Change: Because of code changes in socket.c file for
32bit-userspace, return value changed to EINVAL in case of
32bit-userspace/64-bit-kernelspace.
Test changed to check if 32user/64kernel , then return value should be
checked to EINVAL ,
for other systems return value should be EOPNOTSUPP
Kernel : 3.10.0-123.13.2
