[PATCH net-next] net: psp: use psp_dev_is_registered() in psp_assoc_free()

[Daniel Zahka <daniel.zahka@gmail.com>]

No functional changes.

In code paths that use a psp_dev reference that wasn't obtained from
the psp_devs xarray, e.g. not via psp_device_get_and_lock(), there is
no guarantee that the psp_dev has not been unregistered. The check
here is correct, but it doesn't match other code paths that use
psp_dev_is_registered().

Commit b89769f936a8 ("net: psp: check for device unregister when
creating assoc") is an example of a fix that adds a check for this
after locking a psp_dev. if (psp_dev_is_registered(psd)) vs if
(psd->ops) makes it clear what we are really checking for.
