Fix incremental recursive encrypted receive

Currently, incremental recursive encrypted receives fail to work
for any snapshot after the first. The reason for this is because
the check in zfs_setup_cmdline_props() did not properly realize
that when the user attempts to use '-x encryption' in this
situation, they are not really overriding the existing encryption
property and instead are attempting to prevent it from changing.
This resulted in an error message stating: "encryption property
'encryption' cannot be set or excluded for raw or incremental
streams".

This problem is fixed by updating the logic to expect this use
case.
