This reverts commit abc45b1
Since by default the ondelete attribute of a many2one is `set null`,
this was completely unnecessary to begin with.
Bug caused by this commit:
Unlink a record that has some attachments.
The unlink first removes the record, then its related attachments.
It calls remove_as_main_attachment, which reads the attachment res_model and
res_id. This triggers a check that the related record can be read.
However the related record has already been removed, an exception is raised.
It is thus impossible to unlink a record.
Closes #32563
