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.
