Various anaconda installer fixes

This bug fix advisory corrects several issues in the Red Hat Linux 7.2
installer.

- The installer would not set up SCSI modules to load in the same module
post-install as they did during the install process in some cases.

- Using a driver disk with a newer version of a SCSI driver than the one
shipped in Red Hat Linux would not have the newer drive in the initrd used
for booting the machine post-install.

- Some machines with 3ware controllers would freeze at the partitioning
screen and were unable to install to disks connected to the 3ware
controller.

- Some cases where the installer would traceback incorrectly have been
resolved.

Download the update disk image, then create an update diskette. This can be
done by using the same procedure used to create a boot diskette.

Please note that you must substitute the update disk image filename for the
filename used in the example.

When booting into the anaconda installation program, type "linux updates"
at the boot prompt, followed by any other installation options which are
required (such as "expert" or "text" or "ks"). The installation process
will prompt you to insert the updates disk when it is required, and the
install will then proceed as normal.
