Delay ZFS_PROP_SHARESMB property to handle it for encrypted raw receive

Browse Source 
For encrypted raw receive, objset creation is delayed until a call to
dmu_recv_stream(). ZFS_PROP_SHARESMB property requires objset to be
populated when calling zpl_earlier_version(). To correctly handle the
ZFS_PROP_SHARESMB property for encrypted raw receive, this change
delays setting the property.
