Rob Norris c3496b5cc6 Linux: zfs_putpage: document (and fix!) confusing sync/commit modes
The structure of zfs_putpage() and its callers is tricky to follow.
There's a lot more we could do to improve it, but at least now we have
some description of one of the trickier bits.

Writing this exposed a very subtle bug: most async pages pushed out
through zpl_putpages() would go to the ZIL with commit=false, which can
yield a less-efficient write policy. So this commit updates that too.
