jxiong 16fa68f07d Do not upgrade userobj accounting for snapshot dataset 
'zfs recv' could disown a living objset without calling
dmu_objset_disown(). This will cause the problem that the objset
would be released while the upgrading thread is still running.

This patch avoids the problem by checking if a dataset is a snapshot
before calling dmu_objset_userobjspace_upgrade().  Snapshots
are immutable and therefore it doesn't make sense to update them.
