c5b4450728 qla2x00t-howto clarifications 
Clarify the qla2x00t how-to where necessary:
 - Add instructions to unload the upstream qla2xxx kernel module
   before starting to build the SCST qla2xxx kernel modules.
 - Change the name qla2xxx into qla2xxx_scst in the step for
   loading kernel modules.
 - Replace the instructions for removing the distro-provided qla2xxx kernel
   module by instructions for blacklisting that module and rebuilding the
   initial RAM disk.
 - Prepend all commands that have to be executed by the user by a prompt.
 - Add instructions for RHEL / SUSE next to Debian.
 - Shortened Debian kernel development package list.

Markup changes:
 - Use a CSS style attribute to specify the distance between steps instead of
   using <br><br><br>.
 - Add a missing </li> tag.
