Fix panic in dsl_process_sub_livelist for EINTR 
= Issue

Recently we hit an assertion panic in `dsl_process_sub_livelist` while
exporting the spa and interrupting `bpobj_iterate_nofree`. In that case
`bpobj_iterate_nofree` stops mid-way returning an EINTR without clearing
the intermediate AVL tree that keeps track of the livelist entries it
has encountered so far. At that point the code has a VERIFY for the
number of elements of the AVL expecting it to be zero (which is not the
case for EINTR).

= Fix

Cleanup any intermediate state before destroying the AVL when
encountering EINTR. Also added a comment documenting the scenario where
the EINTR comes up. There is no need to do anything else for the calles
of `dsl_process_sub_livelist` as they already handle the EINTR case.
