qlnxr: Properly initialize the Linux device structure
The driver needs to provide a LinuxKPI device structure to register
itself with the IB subsystem. It was erroneously using a copy of its
FreeBSD device structure for this purpose.
Use linux_pci_attach_device() instead, following the example of the
Chelsio iwarp driver. Also ensure that we don't leak the faked device
during detach.
