api: do not fetch every patch in a patch detail view 404 (v2)

Commit 08c5856 fixed an issue whereby a 404 on the aforementioned URL
could result in a large DB query due to DRF attempting to populate the
'related' list box with all patches on the instance. That was
accidentally reverted in commit fe07f30. "Unrevert" this change.

Fixes: fe07f30 ("Remove 'PatchRelationSerializer'")
Closes: #397
