datapath: Fix build on 2.6.18, which doesn't have "bool" or "false".

The "bool" type is a relative newcomer to the Linux kernel, and it is
still frowned up by some developers, so instead of adding a definition
to our compatibility headers (which is what we usually do), this commit
changes "bool" to "int".
