Alek P 9210e43a16 Don't dirty bpobj if it has no entries
In certain cases (dsl_scan_sync() is one), we may end up calling
bpobj_iterate() on an empty bpobj. Even though we don't end up
modifying the bpobj it still gets dirtied, causing unneeded writes
to the pool.

This patch adds an early bail from bpobj_iterate_impl() if bpobj
is empty to prevent unneeded writes.
