Ian Abbott f4dd2367f3 staging: comedi: 8255_pci: fix possible NULL deref during detach 
`pci_8255_detach()` will be called by the comedi core if
`pci_8255_attach_pci()` returns an error.  It currently assumes that
both `board` (assigned from the return value of `comedi_board(dev)`) and
`devpriv` (assigned from `dev->private`) are non-null, but they might
be null, leading to a null pointer dereference.

`pci_8255_detach()` doesn't need to do anything if either `board` or
`devpriv` are null, so just return early in this case.
