scsi: smartpqi: Stop sending driver-initiated TURs

Browse source

Stop sending driver-initiated TURs to physical devices during driver
load/rescan.

Note: This does not affect SML initiated TURs.

Some Linux kernels can cause lengthy delays in OS boot if the kernel
detects that a drive is being sanitized/erased. We were using TURs to
detect if a sanitize/erase was in progress.

Some devices do not return the TUR in a timely manner, causing driver
load/rescan stalls.
