Bogdan Kolendovskyy d7b8b36082 examples: fix format errors, remove -Wno-format
Logging in series of examples has misuse of "%d" instead of type-appropriate format specifiers.
Fix by changing "%d" to PRIxx macros corresponding to type.
Remove -Wno-format compile flag in those examples that are affected.
