6.6-stable review patch. If anyone has any objections, please let me know.

commit 9023ed8d91eb1fcc93e64dc4962f7412b1c4cbec upstream.
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.
