[PATCH] qlogic lockup fix
If qla2x00_probe_one()'s call to qla2x00_iospace_config() fails, we call
qla2x00_free_device() to clean up. But because ha->dpc_pid hasn't been set
yet, qla2x00_free_device() tries to stop a kernel thread which hasn't started
yet. It does wait_for_completion() against an uninitialised completion struct
and the kernel hangs up.
Fix it by initialising ha->dpc_pid a bit earlier.
