Fix 'zpool remap' freeing race 
The dmu_objset_remap_indirects_impl() logic depends on dnode_hold()
returning ENOENT for dnodes which will be freed and should be skipped.

This behavior can only be relied upon when taking a new hold and
while the caller has an open transaction.  This ensures that the
open txg cannot advance and that a concurrent free will end up
in the same txg (which is critical).  Relying on an existing hold
will not prevent dnode_free() from succeeding.

The solution is to take an additional dnode_hold() after assigning
the transaction.  This ensures the remap will never dirty the dnode
if it was freed while we were waiting in dmu_tx_assign(, TXG_WAIT).

Randomly set zfs_object_remap_one_indirect_delay_ms in ztest.  This
increases the likelihood of an operation racing with the remap.
Converted from ticks to milliseconds.
