[PATCH] scsi: wd33c93: Don't use stale scsi_pointer value

[Finn Thain]

From: Daniel Palmer <daniel@xxxxxxxx>

A regression was introduced with commit dbb2da557a6a ("scsi: wd33c93: Move
the SCSI pointer to private command data") which results in an oops in
wd33c93_intr(). That commit added the scsi_pointer variable and
initialized it from hostdata->connected. However, during selection,
hostdata->connected is not yet valid. Fix this by getting the current
scsi_pointer from hostdata->selecting.
