Fix dprintf format specifiers

Fix a few dprintf format specifiers that disagreed with their argument
types.  These came to light as compiler errors when converting dprintf
to use the Linux trace buffer.  Previously this wasn't a problem,
presumably because the SPL debug logging uses vsnprintf which must
perform automatic type conversion.
