USB: dummy-hcd: Fix uninitialized array use in init()
commit e90cfa813da7a527785033a0b247594c2de93dd8 upstream.
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.
