Subject: [PATCH 10/17] usb: vhci-hcd: Simplify kzalloc usage

Use the shorter variants as suggested by checkpatch.pl:

  CHECK: Prefer kzalloc(sizeof(*priv)...) over kzalloc(sizeof(struct vhci_priv)...)
  CHECK: Prefer kzalloc(sizeof(*unlink)...) over kzalloc(sizeof(struct vhci_unlink)...)

This also improves further maintainability.
