Revert c6537d6742985da1fbf12ae26cde6a096fd35b5c
Backout the tipc changes to the flags int he subscription message. These changees, while reasonable on the surface, interefere with user space ABI compatibility which is a no-no. This was part of the changes to fix the endianess issues in the TIPC protocol, which would be really nice to do but we need to do so in a way that is backwards compatible with user space.
