problem when a dataset has same name as a pool

[mjansens]

Hi nice script. But there could be problems if you have a dataset with the same name as a pool.

so, in check_last_source_snap()
last_snap_source=$( zfs list -o name -t snapshot -H 2> $0.err | grep $SRC_PATH@ | tail -1 )
should be :
last_snap_source=$( zfs list -o name -t snapshot -H 2> $0.err | grep ^$SRC_PATH@ | tail -1 )

Same goes for check_last_target_snap()

I'll take a look asap and fix it.
