	src/external/cddl/osnet/dist/uts/common/fs/zfs: zfs_vnops.c

Log Message:
zfs_putapage: don't try to write to zfs in the page daemon context

basically zfs is not prepared to be called safely for page daemon.

for now, if we found the page dirty, (thus we need to push it into zfs)
just punt with ENOMEM. hopefully the page daemon will find some other
pages to reclaim.

if the system is already full of dirty pages backed by zfs, i suppose
there is no good way to recover. for a longer term, we probably need
some dirty-page throttling mechanism to avoid the situation in the
first place.
