pdfrenderer: Fix uninitialized local variables

Browse Source 
Coverity bug reports:

CID 1270405: Uninitialized scalar variable
CID 1270408: Uninitialized scalar variable
CID 1270409: Uninitialized scalar variable
CID 1270410: Uninitialized scalar variable

Those variables are set conditionally in the while loop
and must keep their values in following iterations, so
they must be declared outside of the loop.
