Brian Behlendorf 78e2139467 Fix dnode_hold() freeing dnode behavior ...

Commit 4c5b89f59 refactored dnode_hold() and in the process
accidentally introduced a slight change in behavior which was
not intended.  The required behavior is that once the ZPL,
or other consumer, declares its intent to free a dnode then
dnode_hold() should immediately start failing.  This updated
code wouldn't return the failure until after it was freed.

When DNODE_MUST_BE_ALLOCATED is set it must return ENOENT, and
when DNODE_MUST_BE_FREE is set it must return EEXIST;

This issue was uncovered by ztest_remap() which attempted
to remap a freeing object which should have been skipped as
described by the comment in dmu_objset_remap_indirects_impl().
