[PATCH 13/14] staging: gasket: page table: remove unnecessary logs

[Todd Poynor]

From: Todd Poynor <toddpoynor at google.com>

Some error logs in page table handling code could only be hit in
cases of programming errors not expected in the current code base, and
aren't likely to be useful on their own.  Remove these.
