Kevin Barnett 2eddf98d01 scsi: smartpqi: Stop sending driver-initiated TURs
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.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
