Tim Chase d2c8103a68 Fix problems receiving reallocated dnodes 
This is a port of 047116ac - Raw sends must be able to decrease nlevels,
to the zfs-0.7-stable branch.  It includes the various fixes to the
problem of receiving incremental streams which include reallocated dnodes
in which the number of dnode slots has changed but excludes the parts
which are related to raw streams.

From 047116ac:

    Currently, when a raw zfs send file includes a
    DRR_OBJECT record that would decrease the number of
    levels of an existing object, the object is reallocated
    with dmu_object_reclaim() which creates the new dnode
    using the old object's nlevels. For non-raw sends this
    doesn't really matter, but raw sends require that
    nlevels on the receive side match that of the send
    side so that the checksum-of-MAC tree can be properly
    maintained. This patch corrects the issue by freeing
    the object completely before allocating it again in
    this case.

    This patch also corrects several issues with
    dnode_hold_impl() and related functions that prevented
    dnodes (particularly multi-slot dnodes) from being
    reallocated properly due to the fact that existing
    dnodes were not being fully cleaned up when they
    were freed.

    This patch adds a test to make sure that zfs recv
    functions properly with incremental streams containing
    dnodes of different sizes.

This also includes a one-liner fix from loli10K to fix a test failure:
