pvrusb2: De-obfuscate code which handles routing schemes
From: Mike Isely <isely@pobox.com>
This change does not change any outward behavior; it merely chops down
some large if-conditions with embedded assignments into something a
little more maintainable for others (I of course never had a problem
with this...).
Priority: normal
