Don't worry, your data is encrypted.  The qemu-img info password check
is unnecessary because qcow2 metadata is unencrypted.

I didn't get a password prompt from qemu-img info on an encrypted qcow2
file using qemu.git/master.

Which version of qemu-img are you using?  Perhaps the unnecessary prompt
has been fixed in a later version.
