Bug 693503: Fix overlong (seemingly infinite) loop of warnings.
When reading a CMAP with values out of range, we can go into a
very long loop emitting the same pair of warnings.
Spot the error case earlier and this give a nicer report.
Problem found in a test file, 3192.pdf.SIGSEGV.b0.2438 supplied
by Mateusz "j00ru" Jurczyk and Gynvael Coldwind of the Google
Security Team using Address Sanitizer. Many thanks!
