Bad printf formatting in frame_zero.cpp

The HotSpot build fails on Zero builds due to a bad argument type using in a print_cr. This causes gcc to issue a warning, which is then turned into an error by the use of -Werror in the HotSpot build.

This was fixed in OpenJDK 9 as an ancillary part of 8075967. We should backport this chunk to 8u so Zero builds can complete.
