zvol_write() can use dmu_tx_hold_write_by_dnode()
We can improve the performance of writes to zvols by using
dmu_tx_hold_write_by_dnode() instead of dmu_tx_hold_write().  This
reduces lock contention on the first block of the dnode object, and also
reduces the amount of CPU needed.  The benefit will be highest with
multi-threaded async writes (i.e. writes that don't call zil_commit()).
