I don't think this is correct, we set these before calling into
xlog_bdstrat, so this means we'll always stip it off after that.

Given that this area is more complicated than the pure macro removal
how about letting it as-is for now?  I have some bigger refactoring
in this area in my queue, and I'll just incorporate the
XFS_BUF_ZEROFLAGS into it.
