[PATCH] USB: dummy-hcd: Fix uninitialized array use in init()

[Bui Quang Minh]

This error path

        err_add_pdata:
                for (i = 0; i < mod_data.num; i++)
                        kfree(dum[i]);

can be triggered when not all dum's elements are initialized.

Fix this by initializing all dum's elements to NULL.
