Make zvol update volsize operation synchronous.

There is a race condition when new transaction group is added
to dp->dp_dirty_datasets list by the zap_update in the zvol_update_volsize.
Meanwhile, before these dirty data are synchronized, the receive process
can cause that dmu_recv_end_sync is executed. Then finally dirty data
are going to be synchronized but the synchronization ends with the NULL
pointer dereference error.
