Fix 'zfs receive -o' when used with '-e|-d' 

When used in conjunction with one of '-e' or '-d' zfs receive options
none of the properties requested to be set (-o) are actually applied:
this is caused by a wrong assumption made about the toplevel dataset
in zfs_receive_one().

Fix this by correctly detecting the toplevel dataset.
