Subject: [PATCH 09/11] pvrusb2-v4l2: Rename dev_info to pdi

There is a macro called dev_info that prints struct device specific
information. Having variables with the same name can be confusing and
prevents conversion of the macro to a function.

Rename the existing dev_info variables to something else in preparation
to converting the dev_info macro to a function.
